Abstract
A theoretical investigation on the classical electromagnetic wave reflection and transmission processes incorporating possible second harmonic generated (SHG) wave in antiferromagnetic FeF$_2$ material has been carried out. The reflection and transmission of SHG wave is strongly influenced by reflection and transmission of first harmonic generated (FHG) wave caused by the s-polarized incoming wave. The percentage of the reflected and transmitted of the SHG wave is much smaller than those of the FHG wave. It is found from this analysis that the ratios $\frac{R^{(2)}}{T^{(2)}_{1}}$ and $\frac{T^{(2)}}{T^{(2)}_{1}}$ (where $R^{(2)}$, $T^{(2)}_{1}$ and $T^{(2)}_{1}$ are the reflectance of the SHG wave, first wave and second wave transmittance of SHG wave respectively) have nonreciprocal behavior when the sign of the constant related to applied external magnetic field $H_0$ as well as the angle of incidence of the incoming wave $\phi$ is reversed.
