Space‐time coding metasurfaces (STCMs) have gained a great deal of achievements in the fields of radar and communication, but they have rarely been explored in the field of electronic jamming. The existing researches use time‐varying surface or phase‐switched screens to realize electronic decepti...
Due to the metasurface units being significantly smaller than the wavelength, during the calculation of the far-field pattern, we can confidently disregard \(f_{(m,n)} (\theta ,\phi )\). This formula proves advantageous for predicting scattering patterns arising from different coding sequences....
