In this paper, we discuss our recent theoretical and experimental results dealing with plasma waves in high electron-mobility transistors (HEMT's) and their applications for sources and detectors operating in millimeter and submillimeter range. Plasma waves in short-channel HEMT's have a resonant response. The HEMT-based source or detector utilizing plasma waves should operate at much higher frequencies than conventional transit-time limited devices since the plasma waves propagate much faster than electrons
