The presence of a resonant medium in the capacitor core essentially changes the character of THz radiation of photoconductive antenna. As a result the coherent radiation at the frequency of elementary excitation (LO phonon or plasmon) is obtained. Though the power of radiation slightly differs from that provided by a usual THz source, the energy of pulse is significantly greater due to longer duration of the pulse. Besides, such a method of THz pulse generation is very useful for THz emission spectroscopy of many materials.
