Enter the expressions for the components for the Incident electric field E0 (SI unit: V/m), if there is an incoming wave from the boundary.

Enter the value or expression for the medium Impedance Z0 (SI unit: Ω). By default, the Z0 uses the value of the vacuum’s impedance. Then select Isotropic, Diagonal, Symmetric, or Full based on the material characteristics and enter values or expressions in the field or matrix.
