DIFFRACTION PROBLEM WITH TIME-VARYING BOUNDARY CONDITIONS

In this study, we investigate waveguide fields modulated by voltage-induced conductivity changes in a layer with ‘p-i-n’ diode-like properties. By applying voltage, we modulate the layer’s conductivity from perfect conductor to free-space conditions, affecting the waveguide’s boundary conditions and inducing diffraction and modulation of incident waves. We employ an upgraded evolutionary approach to electromagnetics (EAE), incorporating a novel format of Maxwell’s equations, to address this complex interaction. This approach offers new insights into wave modulation phenomena and demonstrates the utility of the EAE in exploring dynamic electromagnetic environments. © 2024 by Begell House, Inc.
