Electromagnetic analysis of the experimental setup used to investigate the ratchet effect in two-dimensional electron system under microwave radiation

This paper addresses simulation and analysis of the experimental setup for investigation of ratchet effect on semiconductor heterojunctions with periodic array of artificial semi-disc shaped antidots. For the first time, the electromagnetic incident power across the sample is computed here and the uniformity of the incident electric field linear polarization is characterized. These two preliminary full-wave simulation results are very important for characterisation of the next generation of millimeter and sub-millimeter wave electromagnetic detectors based on the ratchet effect in two-dimensional electron system.
