The Design of Dual Band Stacked Metasurfaces Using Integral Equations

An integral equation-based approach for the design of dual-band stacked metasurfaces that are invariant in 1-D is presented. The metasurface will generate collimated beams at desired angles each band upon reflection. conductor-backed consists two (a patterned metallic cladding supported by a dielectric spacer) one other. designed three phases. First, homogenized and modeled as an inhomogeneous impedance sheet. electric field equation (EFIE) written to model mutual coupling between elements within from metasurface. EFIE transformed into matrix equations method moments. nonlinear solved both bands iteratively resulting complex-valued sheets. In second phase, optimization applied transform these sheets purely reactive suitable printed circuit board fabrication introducing surface waves. third claddings full-wave simulation Using this approach, designed.
