The interaction of two-dimensional electron gas (2DEG) in a solid-state heterostructure with a surrounding slow wave circuit holds the potential for high power THz generation and amplification. The dense 2DEG formed at material interfaces will provid

On the electronic (RF) side of the THz gap, both solid-state transistors and vacuum electronic devices struggle to reach 1mW at 1THz largely due to the diminishing wavelength. Transistors scaled for THz operation have gate lengths << 100nm and cannot

This paper uses field theory to derive the exact dispersion relation of space charge waves in a two-dimensional electron gas (2DEG) located in a dielectric or a dissimilar dielectric waveguide. It is found that the dispersion of a 2DEG can be modeled
Many high power electronic devices operate in a regime where the current they draw is limited by the self-fields of the particles. This space charge limited current poses particular challenges for numerical modeling where common techniques like over-

3-D time-domain modeling of beam wave interaction in a fusion gyrotron is very challenging due to the open-end features of cavity structure and higher-order mode excitation employed to achieve high efficiency. In a previous project, namely GyroPIC, f
