Abstract

In this paper, the goal is to solve an antenna current optimization problem minimizing the stored energy with a desired front-to-back ratio. This minimization problem is non-convex, and we use semidefinite relaxation techniques to find the solution. An initial study on the front-to-back ratio of a dipole shape is presented here.
