Research Abstract

Recently, new structures that have new types of electromagnetic wave propagation performance such as photonic crystal structures have been widely paid attention. Such new structures are expected to be used for developing high performance devices such as night visions, laser radars, and milli-meter wave radars for automatic cruising. In this research, we developed a structural design method for the design of structures that are composed of dielectric materials, and that can change electromagnetic wave propagation performance by applying appropriate and specified forces, based on the concept of the topology optimization method.
