Metasurface-enabled Versatile Matching Layer for Microwave Penetration into the Body

A versatile microwave matching layer that can adapt itself to changing scenarios is presented in order to deliver more power to the human body. The matching layer consists of an antireflection coating slab together with a frequency selective surface which can be fine-tuned to work around 2.5 GHz. An analytical approach to design this versatile matching layer has been offered under certain restrictions. Underlying governing mechanisms of impedance matching have been discussed.
