“…Since K em = K me , we will simply use K em to denote the bianisotropic coupling terms. The details for the derivation of passive, lossless, and reciprocal omega-type bianisotropic GSTCs can be found in the work by Ataloglou et al [37].…”

Electromagnetic metasurface design based on farfield constraints without the complete knowledge of the fields on both sides of the metasurface is typically a time consuming and iterative process, which relies heavily on heuristics and ad hoc methods. This paper proposes an end-to-end systematic and efficient approach where the designer inputs high-level farfield constraints such as nulls, sidelobe levels, and main beam level(s); and a 3-layer nonuniform passive, lossless, omega-type bianisotropic electromagnetic metasurface design to satisfy them is returned. The surface parameters to realize the far-field criteria are found using the alternating direction method of multipliers on a homogenized model derived from the method of moments. This model incorporates edge effects of the finite surface and mutual coupling in the inhomogenous impedance sheet. Optimization through the physical unit cell space integrated with machine learning-based surrogate models is used to realize the desired surface parameters from physical meta-atom (or unit cell) designs. Two passive lossless examples with different feeding systems and far-field constraints are shown to demonstrate the effectiveness of this method.

“…By means of a proper spatial variation of the BCs it is possible to control an interacting electromagnetic field, with a number of practical applications that can be grouped into three main categories: i) manipulation of radiated waves, ii) manipulation of guided waves and iii) conversion between guided waves and radiated waves. The first category includes metascreens for beam shaping and routing in both transmission and reflection [17]- [20], space wave cloaks [21], [22] and imaging devices [23], [24]. The second category includes planar waveguides [25], [26], surface wave cloaks [27], beam shifters and splitters [28], planar lenses [29]- [33].…”

Metasurfaces (MTSs) have emerged in the last years as a promising platform for next generation planar devices in a broad range of frequencies, thanks to their unique field manipulation capability. In particular, in the microwave range this solution is characterized by low-cost, lightweight, and simple integration with electronic circuits, since MTSs can be realized in PCB technology by printing electrically small patches over a dielectric slab. The MTS behavior can then be conveniently described in terms of homogenized boundary conditions of impedance type. Spatial modulation of these boundary conditions allows one to implement a broad class of functionalities, involving space wave or surface wave control, as well as conversion from surface waves to leaky waves. This paper reviews numerical and analytical models, design procedures and microwave applications of modulated MTSs, with particular emphasis on surface wave manipulation, and it discusses expected future developments of this technology.INDEX TERMS Impedance boundary conditions, leaky wave antennas, metasurfaces, periodic structures, planar antennas, planar lenses, surface waves.This article has been accepted for inclusion in a future issue of this journal. Content is final as presented, with the exception of pagination.
