Generation Method of a Calculable Electromagnetic Pulse and its Evaluation

抄録

A method and configuration for generating a calculable electromagnetic pulse is proposed in which the electromagnetic pulse is radiated from a small monopole antenna placed near the edge of a semi-infinite ground plane. The monopole antenna is excited by an impulse train. The radiated electric field at a distance from the edge is calculated by the waveform of the excited impulse with the assistance of the Uniform Theory of Diffraction (UTD) to include the effect of diffraction from the edge of the ground plane. The electric field is also reconstructed by signal processing using the complex antenna factor (CAF) of a receiving wide-band antenna. The estimated systematic effects and the agreement of the calculated and reconstructed waveforms show that the generated electromagnetic pulse has a possibility to be used as a reference wave for electromagnetic pulse measurements.
