Description
Boyu Sima and ten colleagues build an electromagnetic surface that can switch between absorbing microwaves and converting their polarization. The design stacks tightly coupled dipole antennas over a ground plane loaded with interchangeable radio-frequency circuit boards. Swapping the back board swaps the function, making the surface modular and reconfigurable.
The array works across roughly four to thirteen gigahertz with wide scanning angles. With the absorption board it absorbs across most of that band for both polarizations; with the conversion board it converts polarization over a similar range. Simulations and experiments agree. The authors point to active stealth, adaptive camouflage, and intelligent communications as applications for the modular surface.
