Hello, I recently just started a Masters program in Electrical Engineering with a focus on Electromagnetics. I'm also currently working for a large engineering company. I'm considering purchasing the student version of Matlab so I can work on antenna problems. What packages should I consider purchasing, such as SimRF and the RF Toolbox? It would also benefit me to learn Matlab, or other simulation software for work. Another option is MultiSim from National Instruments. Also, LTSpice which is free.
