The Full Wave Solver takes into account all terms of Maxwell's equations. Due to this the wavelength can be smaller than the analyzed part dimensions and even very high frequencies are allowed. In the time domain results are the electric and magnetic field for every time step.

Theory and Basics
The basis equations:
(1) rot h = j + δt d
(2) rot e = -δt b
(3) div b = 0
(4) b = µ h
(5) d = ε e
(6) j = σ e
The following a-v-formulation is used for 3D
Magnetic vectorpotential a,
electric scalar potential v:
(7) b = rot a
(8) e = -δt a – grad v
