Abstract
This paper presents a method of a real time simulator for a computer aided design of microwave industrial products, in particular, for a shape design. According to progress of PC performance and simulation technology, numerical simulations are widely used in microwave product designs such as electromagnetic noise analysis, high frequency filter and so on. However, iterative microwave simulations for finding appropriate microwave product shapes require a large computer cost. It is shown that the real time microwave simulator based on the FDTD method can reduce a total simulation cost of the shape design to unify all stages of pre-process, calculation and post-process in the simulation.
