Abstract

Based on the effective medium theory, we designed a simplified transformation media bending waveguide by use of only three kinds of isotropic material in an alternating layered structure. The design can be used to guide incoming waves smoothly along the bending part of a waveguide with slight distortions. Numerical simulations are performed to illustrate its functionality.
