Transient Response of Optically-Controlled Microwave Pulse through Open-Ended Microstrip Lines

Transient Response of Optically-Controlled Microwave Pulse through Open-Ended Microstrip Lines

In this paper we examine the reflection characteristics of dielectric microstrip lines with open-ended termination containing an optically induced plasma region, which are analyzed by the assumption that the plasma is distributed homogeneously in laser illumination. The characteristics impedances resulting from the presence of plasma are evaluated by the transmission line model. To estimate theoretically the characteristic response of identical systems in the time domain, the Fourier transformation method is evaluated. The reflection characteristics of time and frequency response in microwave systems have been calculated using an equivalent circuit model.
