Pulsed Electromagnetic Plane-Wave Interaction With a Time-Varying, Thin High-Dielectric Layer
Martin Štumpf, Giulio Antonini, Jonas Ekman
Abstract
An analytical approach to the analysis of electromagnetic (EM) reflection and transmission of a plane wave at a time-varying, high-dielectric thin layer is described. Closed-form expressions for the time-domain (TD) reflection and transmission coefficients are derived and successfully validated using an equivalent circuit representation. The cases of the constant-to-linearly increasing and harmonic temporal profiles are analyzed in detail. Illustrative numerical examples demonstrating the pulse shapes of the temporally modulated EM fields are presented.
