Near-Field Thermal Transistor [PDF]
Physical Review Letters, 2014 Using a block of three separated solid elements, a thermal source and drain together with a gate made of an insulator-metal transition material exchanging near-field thermal radiation, we introduce a nanoscale analog of a field-effect transistor which is able to control the flow of heat exchanged by evanescent thermal photons between two bodies.

Near-Field-Focused Microwave Antennas: Near-field shaping and implementation [PDF]
IEEE Antennas and Propagation Magazine, 2017 Focusing the electromagnetic field radiated by an antenna at a point in the antenna near-field (NF) region is a wellknown technique to increase the electromagnetic power density in a size-limited spot region close to the antenna aperture. This article encompasses the basic working principles and the applications of the NF-focused (NFF) microwave ...
