Abstract

Based on the coordinate transformation theory, we propose a way to manipulate the field distribution in three-dimensional waveguides filled with the designed material. In this work, we show that the designed transformation media can concentrate the electromagnetic field more extremely around the center of the rectangular cross-section inside the straight waveguide. Furthermore, high concentration of the field distribution inside the waveguide bend is also performed well. Numerical simulations demonstrate that the electromagnetic wave can propagate without any signal destruction and conserve the original propagation mode at receiver side.
