Analysis of Screening Effects on Terahertz Photoconductive Devices using a Fully-Coupled Multiphysics Approach
Liang Chen, Hakan Bagci
The terahertz current generated by a photoconductive device (PCD) saturates as the power of the input optical pump is increased. This behavior is induced by various screening effec…
A hybridizable discontinuous Galerkin method for simulation of electrostatic problems with floating potential conductors
Liang Chen, Ming Dong, Ping Li +1
In an electrostatic simulation, an equipotential condition with an undefined/floating potential value has to be enforced on the surface of an isolated conductor. If this conductor…
Efficient Discontinuous Galerkin Scheme for Analyzing Nanostructured Photoconductive Devices
Liang Chen, Kostyantyn Sirenko, Ping Li +1
Incorporation of plasmonic nanostructures in the design of photoconductive devices (PCDs) has significantly improved their optical-to-terahertz conversion efficiency. However, this…
Multiphysics Simulation of Plasmonic Photoconductive Devices using Discontinuous Galerkin Methods
Liang Chen, Hakan Bagci
Plasmonic nanostructures significantly improve the performance of photoconductive devices (PCDs) in generating terahertz radiation. However, they are geometrically intricate and re…
Steady-state Simulation of Semiconductor Devices using Discontinuous Galerkin Methods
Liang Chen, Hakan Bagci
Design of modern nanostructured semiconductor devices often calls for simulation tools capable of modeling arbitrarily-shaped multiscale geometries. In this work, to this end, a di…
Scattering theory and cancellation of gravity-flexural waves of floating plates
Mohamed Farhat, Pai-Yen Chen, Hakan Bagci +2
We combine theories of scattering for linearized water waves and flexural waves in thin plates to characterize and achieve control of water wave scattering using floating plates. T…
