Abstract :
Plasma wave propagation along an ungated two Dimensional Electron Gas (2DEG) layer of a hetrostructure is studied. It is shown that the wave can be useful in amplification of THz signals. An analytical solution of Maxwell and Hydrodynamic equations is presented. This method provides an insight into electromagnetic modes allowed to propagate along the 2DEG as electrons are in motion with constant average drift velocity. Besides, wave impedances of the modes are illustrated. Afterwards, a simple matching network design for input and output ports of the 2DEGs is developed.
