The interactions of terahertz pulses of electromagnetic radiation with optically-excited free charge carrier plasmas on the surface of semiconductors are studied. The influence of the plasma layer on the Brewster effect and total internal reflection is analyzed. It is shown that the changes in transmission and reflection caused by the electron plasma layer can be used to modulate terahertz radiation.
