For the comparison, we obtain an exact full-wave solution of two-dimensional focusing lens problem and use it as a benchmark for testing and validation of asymptotic models being proposed.EnglishDielectricLensMicrowaveInfraredTHzHigh frequencyAsymptoticFull wavePhysical opticsSimulationModelingConference Paper10.1109/ICATT.2007.4425123
