I am trying to simulate DRA in free space with CST and if possible, does anyone have some matlab codes to obtain the multiple modes in a DRA in free space? I was trying to use the eigenmode solver in CST to obtain the modes but the modes obtained were inaccurate according to the solver. I used an airbox to create air interface beyond the DRA and with perfect magnetic conductor at the boundaries. How big should the box be to get a decent accuracy?[/b]
