Dielectric Parameters and Wave Propagation Characteristics in Multilayer Media

In order to understand the plane wave propagation characteristics in multilayer media, selecting the adjacent 3-layer dielectrics, two boundaries surfaces for example, models of plane wave propagation were established within each layer. Simulation results show that both the incident and reflected waves were in the ordinary dielectric, their synthesis wave wasn’t complete stationary wave; Imaginary part of complex permittivity was attenuation factor. Other results also show when the wave struck a dielectric layer normally, the dielectric wave impedance and the thickness of the layer met the condition of a quarter wavelength matching layer, there was no reflected wave. This conclusion is of great value in many engineering and practical applications.
