Transmission and Reflection Coefficients in Time-Domain for a Dielectric Slab for UWB Signals

The Time-Domain (TD) solutions for the reflection and transmission through a dielectric slab case are presented. In contrast to other existing solutions, the proposed ones can incorporate correctly the multiple internal reflections inside the slab in simple and easy-to-use closed forms. The comparison of the proposed solutions against the numerical inverse Fourier transform of the received waveforms as these were calculated in the frequency domain reveals an extremely good agreement and validates the correctness of the TD forms.
