basic information
FIMMWAVE is a suite of robust and fully vectorial mode solvers for 2D+Z waveguide structures. It supports a large number of complementary algorithms which allows it to solve a large variety of waveguides which may be made of any material and of almost any geometry. FIMMWAVE can also model propagation in 2D and 3D structures thanks to its propagation module FIMMPROP.
