Three dimensional electric field measurement method based on coplanar decoupling structure

Abstract

This paper proposes a simple and precise way to measure three dimensional (3D) electric field (E-field). By means of creating and deriving a coupling sensitivity matrix, the 3D E-field can be accurately measured by using three electric field sensing elements distributed on a plane. The cross interferences between these sensing elements can be effectively eliminated. Finite element simulations and experiments have demonstrated that the measured result is accurate for any random rotation angle.
