EC.00001: The theory of the anti-maser: coherent perfect absorption of RF Michael Aviles, Anthony Mazzocco, Jim Andrews, Nathan Dawson, Michael Crescimanno The radio frequency (RF)-analogue of the anti-laser is developed using four terminal network theory combined with the telegrapher's equation. We describe solutions of the Coherent Perfect Absorption (CPA) condition that are interpretable as the slab dielectric anti-laser. We find a host of other solutions, some of which have no simple optical analogue. Broadband solutions are found which hint at the possibility of a new type of asymmetric transient CPA phenomenon, and point out that this study suggests a potentially new low loss, reversible RF devices.

EC.00002: Experimental demonstration of the anti-maser Anthony Mazzocco, Michael Aviles, Jim Andrews, Nathan Dawson, Michael Crescimanno We denote by ``anti-maser'' a coherent perfect absorption (CPA) process in the radio frequency domain. We demonstrate several experimental realizations of the anti-maser suitable for an advanced undergraduate laboratory. Students designed, assembled and tested these devices, as well as the inexpensive laboratory setup and experimental protocol for displaying various CPA phenomenon. [Preview Abstract] |

EC.00003: Understanding temperature tuning of the all polymer co-extruded laser Michael Crescimanno, Jim Andrews, Michael Aviles, Nathan Dawson, Joshua Petrus, Anthony Mazzocco, Ken Singer, Eric Baer, Hyunmin Song We investigate the effects of elevated temperatures on a few types of all-polymer multilayer films that were fabricated using a co-extrusion melt-process technique. We report on the anisotropic thermal expansion of the multilayer films, which affects the photonic crystal structure via constituent wise induced anisotropic strains and a change in the relative refractive indices. In addition to the characterization of these films in the temperature range of approximately 20-95 degrees C, we show the application to non-contact temperature sensing and wavelength tuning of all polymer Distributed FeedBack (DFB) lasers and Distributed Bragg Reflector (DBR) lasers.

EC.00004: An Apparatus for Verification of Absolute Calibration of Quantum Effiency for Charge-Coupled Devices Rebecca Coles The LBNL Microsystems Laboratory produces backside illuminated, high resistivity, p-channel, charge-coupled devices (CCDs). A system was developed to test the quantum efficiency (QE) of the CCDs; the percentage of electrons that are emitted from the CCD surface per amount of light that it's exposed to. The QE system was designed and constructed to test CCDs of a much smaller size then what is currently produced. To continue testing, I redesigned the QE apparatus to make room for the new, larger size, CCDs while still preserving measurement accuracy. I removed the photodiode that formally sat alongside the CCD in the Dewar, and installed it in a separate container. Instead of the CCD and the photodiode taking flux measurements simultaneously, the processes are now preformed separately. The error caused by the separation has remained less than 1.78{\%}.

EC.00005: The Arithmetic of Events and a New Theory of Gravitation Malek Abbasi Of fundamental importance in physics is the concept of event. This study tries, first, to provide a mathematical background showing how must deal with these events and based on what laws the watches, another important concept used frequently in this research, record them. Armed, then, with this mathematical background, the Gravitational Clouds Theory, a novel theory of gravitation concerning the role of the matter and energy in the universe, is proposed. This completely new theory leads to miscellanies results some of which are: the second Einstein's postulate; the well known identity E = mc2; the time-dilation phenomenon and Fitzgerald-Lorentz contraction. This theory will also explain why indeed we never feel the speed of the Earth, what is the origin of Dark matter-energy and many other extraordinary results associated with cosmology.

EC.00006: Extending Newton's Apsidal Theorem Cameron Tuckerman, Ulrich Zurcher For the Kepler potential $\Phi_{0} = \mu/r$, the orbit is closed and the apsidal angle is a full circle $\Delta \Theta = 2 \pi$. For the potential $\Phi (r) = \mu/r^{2-n}$, the orbit is open [Bertrand's theorem] and the trajectory has the general shape of a rosette. Newton found an expression for the Apsidal precession for small eccentricities $\Delta \Theta = 2 \pi/\sqrt{n}$. We extend this result for arbitrary orbital parameters; we introduce a description in terms of an effective angular momentum and a Keplerian potential $\Phi_{\rm eff} = - \rho/r$. We find an exact expression for the Apsidal precession. For $|n|<0.3$, we find $\Delta \Theta = 2\pi/n^{\alpha}$ and find expressions for the exponent $\alpha$ that are correct with 1\%. We discuss possible applications to the orbits of stars in elliptical galaxies. [Preview Abstract] |

EC.00007: GEMS (Gravity Electro-Magnetism Strong) SU(5) Theory and The Prediction of Exchange Boson Masses John Brandenburg The GEMS SU(5) [1] theory includes short range Nuclear Forces in the GEM unification theory [2], where the importance of the square root of the proton-electron mass ratio: $\sigma$ = 42.8503 was found. The creation of mass by a Higgs field coupling must, by the Equivalence Principle, be viewed in the context of General Relativity. This is done here using Kaluza-Klein theory in a Feynman-Hawkings path integral formalism. GEM theory, quantum concepts of virtual particles, and ZPF (Zero Point Fluctuation) allow understanding of the Strong Force and Weak forces as the extension of electrodynamics in the quantum limit. The Strong and Weak forces are found to be associated with EM models of the electron and proton as finite sized structures respectively. Higher order Mie resonances off the EM ``mass at a distance'' structures associated with the electron, proton and fifth dimension generate the quanta with masses of the pion m$_{\pi}$ = 2 m$_{e}$ /$\alpha \cong$ 140.0 MeV and Z boson: m$_{Z}$ = 2$\sigma$ m$_{p}$ = 80.4 GeV. The $\eta _{c}$ meson m$_{\eta}$ = 2980 GeV is identified with the 5$^{th}$ dimension compactification force mediated by the Radion field. Another particle associated with this mass inducing field is the ``Radion'' or Higgs scattering quanta off the fifth dimension with a mass $\sigma$m$_{\eta} \cong$ 128.6 GeV which is the Higgs Boson. A GEMS SU(5) Georgi-Glashow model, is proposed, where the unification energy is now the Planck energy.\\[0pt] [1] Brandenburg, J.E.

EC.00008: Derivation of the Schwartzchild Metric From the ``Self Censorship'' of the ZPF (Zero Point Energy) in the GEM Theory John Brandenburg The GEM theory (1) links the EM stress tensor directly to the metric tensor by the principle of ``self censorship'' of the ZPF (2) where the definition of g$_{uv}$ = F$_{uw}$F$^{w}_{v}$/ 4 for Planck scale fields makes the stress tensor vanish even when fields are present. The first order form of the metric is recovered as Lorentzian due to alternating regions of strong electric and magnetic fields similar to that seen in models of spacetime in ``Loop Gravity,'' where the model admits perturbations. The GEM ExB drift models of gravity is used The first order perturbations on the fields are considered to be of the order of the fine structure constant alpha. Radiation fields due to a single charged particle of mass M fall off as 1/r and give the values (G=c=1) g$_{tt}$ = 1-2M/r and g$_{rr}$ = (1-2M/r). (1) Brandenburg, J.E.
