Study on Reflection and Transmission Characteristics of Electromagnetic Waves Propagation in Different Medium Based on Constitutive Parameters

Plane waves are a fundamental concept in electromagnetic (EM) waves propagation and widely applied as means for analyses in various fields. This paper deals with the study on reflection and transmission characteristics of EM waves propagating in different medium based on the constitutive parameters. There are three constitutive parameters focused on the study, namely permittivity (ϵ), permeability (µ), and conductivity (σ). The properties of plane waves propagate in two or more different mediums, i.e., reflection and transmission coefficients, are calculated using the formulas derived from the constitutive parameters. The simulations are also carried out to verify the calculation results by the formula derivation. The results show good agreements between the calculations and the simulations, with the errors less than 1% in average, demonstrating the feasibility of calculation for material characterization.
