A method for estimating the electromagnetic power delivered by the front-end module used to investigate the ratchet effect in two-dimensional electron Gas system under microwave radiation

This paper proposes a method for estimating the amount of electromagnetic incident power on the surface of a semiconductor sample, delivered by the front-end module used to investigate the ratchet effect in two-dimensional electron gas system under microwave radiation. The proposed approach, based on intensive full-wave electromagnetic simulations, allows us to establish a simple formula to compute the incident power at the surface sample. The described method is validated using indirect measurements.
