From: Fast decomposed method to devise broadband polarization-conversion metasurface
Near-field plots for three different frequencies. Distribution of the electric field magnitude and electric near field (arrow direction denotes the direction of the vector of [Re{Ex}, Re{Ey}, Re{Ez}], and its length denotes the amplitude of the near field) in the top panel and the real part of the z-component of the near field (\(E_z\)) in the bottom panel on the metallic parts of the metasurface unit cell at frequencies of (a) 15 GHz, (b) 23.4 GHz and (c) 27.4 GHz. The electric field is normally incident along the y-direction. In the following simulations, \(P = {5}\,\text {mm}\), \(L_{1} = {6.25}\,\text {mm}\), \(L_{2} = {2.5}\,\text {mm}\), \(h = {2.5}\,\text {mm}\), and \(d = {0.4}\,\text {mm}\).
