Abstract: Determining electromagnetic response of sample structure having predetermined bulk permittivity and permeability, to electron and radiation pulses, includes calculating electron pulse response of sample structure to electron pulse excitation, using finite-difference time-domain method. Electron pulse excitation is represented by non-singular current source driven by relativistic moving non-Coulombian electron charges, electron pulse response is calculated based on interaction of electron pulse excitation with electromagnetic modes of sample structure at laboratory frame, and electron pulse response depends on bulk permittivity and permeability of sample structure, calculating radiation response of sample structure to electromagnetic radiation excitation, using finite-difference time-domain method. Radiation response depends on bulk permittivity and permeability of sample structure, and providing electromagnetic response of sample structure by superimposing electron pulse response and radiation response.
