A low-profile planar microwave lens based beam pattern for millimeter wave physiotherapy

摘要

Due to the non-ionizing radiation, microwave has the advantage to reduce the injury for tissue and organs compared with X-ray and CT. In most situations, however, the microwave antenna is used by directly illuminating the human tissue and most energy is radiated into free space which leads to the low efficiency and poor treatment effect. We proposed a planar millimeter lens which could gather the electromagnetic radiation into a limited area in the superficial human tissue to realize the physiotherapy.
