Design study of ultrahigh-speed microwave simulator engine

摘要

A design study of microwave simulator engine is presented in this paper. Taking note the simplicity and duality of data flow in finite-difference time-domain (FDTD) scheme, conceptual and hardware designs of the engine are shown for two-dimensional wave phenomena. To store field values in individual SRAMs, efficient use of digital hardware resources is achieved and the engine is constructed by very small size hardware. Based on the design study, a prototype hardware is made and basic operation is confirmed.
