FPGA-Based FDTD Accelerators for 2DEG Plasma-Wave Device Modeling at THz

Plasmonic waves supported on 2DEG devices at terahertz (THz) frequencies are important for future high-bandwidth wireless communication and imaging systems. The design of such devices requires solution of computationally intensive Finite Difference Time Domain (FDTD) based multiphysics models which can be slow even with the use of GPUs. In this work, application-specific custom computing architectures based on reconfigurable deep nano-CMOS FPGA technologies, such as the 14nm Xilinx ZynQ RF SoC, are explored for solving the above problem using massively-parallel fine-grain pipelined multirate systolic-array processors.
