Non-Euclidean cloaking was recently proposed by combining non-Euclidean geometry and transformation optics. As the coordinate transformation is non-singular, cloaking may be broadband. Such a cloak has initially been designed for the regime of geometrical optics. Here we demonstrate that the cloaking device can even function in extreme wave optics when the working frequencies are quantized related to the spherical harmonics. Numerical simulations were performed to illustrate the cloaking effect.
