Abstract :
Analytical model is developed and used to calculate spatial distribution of sheet electron density in the channel of grid-grating gated HEMT structure and resonant frequencies of plasma waves excited in the channel. It is shown that plasma resonances in realistic structures deviates from those predicted by ideal model.
