TE TM fields calculation

[zdarova]

i was wondering if there is some software that can calculate this fields, the H,E one known the incidental one in a system of 2 corps (different n)
also for antennas...the spectrum analisis for different angle max or min?
i have an exam and the teacher is letting us use the notebooks,
sorry for my bad english, i am from italy

It is not clear what you are asking. There exists software which can calculate numerically some modes of oscillation of a cavity or a waveguide or the like. It's finite element (of a variant like finite differences ....) software.
