To address this problem, we present Fourier operations on a time-domain digital coding metasurface and propose a principle of nonlinear scattering-pattern shift using a convolution theorem that facilitates the steering of scattering patterns of harmonics to arbitrarily predesigned directions. Introducing a...
Fourier convolution operationsEncoding metasurfaceWe propose an encoding metasurface with three-layers C-shaped unit cell structure. The transmission phase from 0 to 2蟺 can be obtained by using different rotation angles of Pancharatnam-Berry encoding elements. The Pancharatnam-Berry encoding metasurfaces ...
This paper presents a coding metasurface specifically designed for 5G communication applications, operating at a frequency of 3.5 GHz. The design employs a unique annular metasurface unit structure capable of achieving both single-beam and dual-beam functionalities. Through convolution operations, precise ...
