ABSTRACT
The two-dimensional (2D) or three-dimensional (3D) multiway power dividers based on transformation optical theory are proposed in this paper. It comprises of several nonisotropic mediums and one isotropic medium without any lumped and distributed elements. By using finite embedded coordinate transformations, the incident beam can be split and bent arbitrarily in order to achieve effective power division and transmission. In addition, the location of the split point can be employed to obtain unequal power dividers. Finally, several typical examples of the generalized power divider without limitation in 3D space are performed, which shows that the proposed power divider can implement required functions with arbitrary power division and arbitrary transmission paths. The excellent simulated results verify the novel design method for power dividers.

Ideal coordinate transformations.(a) Ideal coordinate transforming paths of 2D-TWPD. θxy is determined by the parameter a. The port boundary is used to serve as an excitation source of electric field. (b) Ideal coordinate transforming paths of 3D-TWPD. θxy and θyz are determined by parameters a and k, respectively. It should be noted that the Gaussian beam excited at Port 1 acts as the incident beam.
