Abstract :
In the following article a new algorithm for retrieval of electromagnetic currents from known radiated fields is presented. The method, based on matrix formulation, solves inverse radiation problem over perfect electric conductor (PEC) surfaces from near field measurements. The final goal is the diagnosis and characterization of any kind of antennas, independently of the complexity of the antenna geometry. Code has been optimized in time and memory consumption, using matrix decomposition and iterative techniques
