The interaction of slow circuit waves with drifting carrier waves in solids is analyzed to investigate the wave characteristics and to predict the wave amplification.
A general dispersion relation for the coupled waves traveling along a finite semiconductor slab is developed by analyzing the interaction between two waves.
The effects of collision, diffusion, insulator thickness, semiconductor thickness and substrate material are included in the analysis.
The results indicate the feasibility of a simple amplifier device in the microwave frequency range. The experimental results are presented to confirm the general feature of the theoretical analysis.
The maximum gain of 6.8db was obtained through the coupled circuit.
