Abstract Independent control of electromagnetic (EM) waves by metasurfaces for multiple tasks are highly desired and is the recent hot topic of research. In this work we contribute a polarization insensitive frequency multiplexed 2-bit coding metasur

Abstract A long‐held tenet in computer science asserts that the training of deep learning is analogous to an alchemical furnace, and its “black box” signature brings forth inexplicability. For electromagnetic metasurfaces, the related intellige

An ideal metasurface design encompasses the control of all the degrees of freedom of electromagnetic (EM) waves. Here, we present a digital coding metasurface optimized for dual-band operations (in K and Ka band) for orthogonal polarizations. The pro

In this paper, a 4-bit reflective coding metasurface with the polarization-insensitive unit cell is designed for wideband radar cross section (RCS) reduction. The metasurface unit has rotational symmetry; therefore, it produces the same electromagnet
