“…The impedance is directly extracted from the complex reflection (R) and transmission (T) coefficients. As demonstrated in [16], R and T can be related to the sheet impedances of a periodic metasurface for a normally incident plane wave,…”

Huygens' principle is a well-known concept in electromagnetics that dates back to 1690. Here, it is applied to develop designer surfaces that provide extreme control of electromagnetic wave fronts across electrically thin layers. These reflectionless surfaces, referred to as metamaterial Huygens' surfaces, provide new beam shaping, steering, and focusing capabilities. The metamaterial Huygens' surfaces are realized with two-dimensional arrays of polarizable particles that provide both electric and magnetic polarization currents to generate prescribed wave fronts. A straightforward design methodology is demonstrated and applied to develop a beam-refracting surface and a Gaussian-to-Bessel beam transformer. Metamaterial Huygens' surfaces could find a wide range of applications over the entire electromagnetic spectrum including single-surface lenses, polarization controlling devices, stealth technologies, and perfect absorbers.

“…The recently proposed metasurface is a two-dimensional array of subwavelength scatterers [1][2][3][4][5][6][7][8][9]. It is a promising way to manipulate electromagnetic (EM) wave propagation because of the designable feature of its surface impedance, which uniquely determines the EM field behavior.…”

Abstract-Metasurfaces, due to its designable surface electric and magnetic impedances, have largely enhanced electromagnetic wave manipulation techniques. The conventional approach to realize the surface magnetic impedance requires non-planar structures, such as metallic loops, which is not easy to fabricate, especially at optical frequencies. In this work, we theoretically and rigorously prove that effective surface magnetic and electric impedances can be obtained using parallel electric metasurfaces. A synthesis method is presented which allows independent designs of surface electric and magnetic impedances. Finally, a polarization converter with high energy efficiency is designed using the proposed impedance synthesis method for verification. The proposed synthesis method is favorable for reducing fabrication complexities.

“…As two-dimensional metamaterial structures, they do not suffer from the disadvantages associated with volumetric metamaterials, such as bulkiness, excessive losses and fabrication difficulty [1]. Metasurfaces have been employed to control the reflection and transmission of electromagnetic waves [2], realize generalized refraction [3] and reflection-less refraction [4] for plane-waves, single-layer perfect absorbers [6] and reciprocal [7] and non-reciprocal [8,9] polarization rotators.…”

Abstract-Two exact approaches to synthesize metasurfaces for time-harmonic waves are discussed. The first approach is a spectral approach based on wave momentum conservation. Here, the spectral approach is applied to scalar and paraxial wave transformations. This approach effectively allows the arbitrary translation of the transformation plane parallel to the metasurface. The second approach is a direct-space approach based on the extraction of the susceptibility tensors of the metasurface elements. This approach is applied to vectorial field transformation and can be used for single or multiple transformations. An example of wave transformation by a metasurface is illustrated for each of the two approaches.
