Description
Summary:In this work, a device capable of acting as a multiplexer (MUX) and demultiplexer (DEMUX) for electromagnetic waves in gigahertz range is designed and modeled numerically. The device is based on optimized dielectric periodic structures. It can combine signals of different central frequencies injected at its input ports to a single output port, thus acting as a MUX. Reciprocally, the device can separate mixed signals of different frequencies to specific output ports, acting as a DEMUX. To this aim, specific imperfections are introduced into the periodic structure. The design and analysis of the device are performed using the finite-difference time-domain method (FDTD). Transfer functions between pairs of input and output ports are calculated and used to define the design metrics
