Asymmetric Electromagnetic Modes on a Two-Dimensional InSb-Air-InSb Waveguide
arXiv:2304.04536
Abstract
In this paper, the asymmetric propagation of electromagnetic waves inside a two-dimensional air slit cut in an InSb slab is studied. It has been shown that due to the anisotropic magnetic properties of InSb under a DC magnetic bias, forward and backward waves show different field patterns inside the air slit. The proposed waveguide can have potential asymmetric applications in mmWave and sub-THz regions.
