文摘

In this article, a novel approach, called Rays Inserted Method (RIM), is introduced to design dielectric optical devices. In this approach, some rays are inserted between two ends of desired device and then the refractive index of the points along the route of rays are obtained. The validity of the introduced approach is verified by designing three types of optical devices, i.e. power splitter, bend, and flat lens. The results are confirmed with numerical simulations by the means of FDTD scheme at the frequency of 100 GHz.
