“…The final design step is the copper trace design procedure. The copper traces themselves are in the form of so-called "dogbones" [22], [23]. As with the impedance sheets, we wish to relate the scattering parameters of the desired unit cell to the scattering parameters of the three-layer copper trace unit Fig.…”

“…Unlike the previous case with the impedance sheets, the optimization of this structure is much more difficult. To find a suitable design, we employ a lookup table strategy [23], wherein we use a pre-populated table containing a list of copper trace configurations and their associated scattering parameters. This table is generated by semi-randomly simulating individual unit cells in Ansys HFSS and extracting their scattering parameters.…”

<p>In this paper, we consider two design procedures for a cascaded metasurface pair. For a particular application, we present and evaluate data from simulations and experiments. We discuss the details and limitations of the two design algorithms, the fabrication process, and the measurement procedure. In particular, we highlight difficulties with respect to the measurement and analysis, as well as the techniques used to address these difficulties.</p>

“…The desired pattern is obtained from the power pattern of an array of line sources and is the same as the desired power pattern used in[13] 2. The measured result is reported at 10.3 GHz as we had a −0.2 GHz frequency shift as compared to the design frequency.…”

<p>Electromagnetic forward and inverse solvers are considered for the analysis and design of electromagnetic metasurfaces. This paper reviews (i) a forward solver that takes the surface susceptibilities of metasurfaces and calculates their scattered fields and (ii) an inverse solver that takes user-defined desired power patterns and outputs the required metasurface properties. An omega-bianisotropic transmitting metasurface is then fabricated and measured to evaluate the performance of these forward and inverse solvers.</p>
