Abstract

A method of direct transformation of a video pulse into a radio pulse in a microstrip transmission line (TL) filled with a nonlinear medium on the basis of a multilayer heterostructure (MLHS) with asymmetric barriers (AlAs/n-GaAs/Al/sub x/Ga/sub 1-x/As/n/sup +/GaAs/AlAs)/sub N/ has been suggested by A.M. Belyantsev and A.B. Kozyrev (Int. J. Inf. and MM Waves, vol. 18, p. 1169, 1997). The mechanism for the transformation is the electromagnetic shock-wave (EMSW) front instability towards the forward wave running in synchronism with it. In this paper, we study the special features of the direct transformation of a video pulse into a radio pulse in a bi-modal electrodynamic system of the coupled TL type with different types of dispersion allowing backward wave propagation.
