 $a ̂_{k}k_{1}$ = $a ̂_{x}$ ( - j ) + $a ̂_{y}$ ( - j ) unit of ($k_{1}$: rad/m) $a ̂_{k}k_{2}$ = $a ̂_{x}$ ( - j ) + $a ̂_{y}$ ( - j ) unit of ($k_{2}$: rad/m)

Parameters:

 $E_{10}$: Magnitude of $E$ field for the first plane wave $E_{20}$: Magnitude of $E$ field for the second plane wave $θ$1: Angle of propagation of the first plane wave. $θ$2: Angle of propagation of the second plane wave. $ε_{r}$: Relative permittivity of medium $μ_{r}$: Relative permeability of medium ${σ}$: Conductivity $f$: Frequency
 Red/Blue circle: $H$ field of positive/negative perpendicular component.
