2-D WFS Approach Through Field Transformation—Application to Performance Prediction in Standard Antenna Simulators

This paper presents a 2-D wavefield synthesis approach directly implementable in standard antenna simulation software. The approach uses a field transformation matrix and two array sets to design vertically and horizontally polarized wavefields, implemented with thin electric dipoles for their simpl...
