Transient reflection of TM-polarized plane waves from a Lorentz-medium half-space.
The time-domain reflection coefficient for a TM-polarized plane wave obliquely incident on a Lorentz-medium half-space is determined analytically by inversion of the frequency-domain reflection coefficient. The resulting expression contains only the convolution of simple functions. This allows the temporal behavior of the reflection coefficient to be predicted, and the relationship between the material parameters and the oscillation of the response to be easily identified. The time-domain expression is validated numerically through comparison with the inverse fast Fourier transform of the frequency-domain reflection coefficient.
