Outline of Final Research Achievements

The purpose of this study is to develop a dielectric radome with an arbitrary shape, and to establish a method to optimize and fabricate its shape. In order to search for an unique shape as compared with the conventional shape, the topology optimization that can directly change the shape of the object is used for the design of the dielectric radome. To obtain a smooth shape, 3-dimensional topology optimization using the normalized Gaussian network (NGnet) is proposed. From some design example, the presence method has good performance. Moreover, it is shown that the optimized dielectric lens can be fabricated by the 3D printer.
