Circuit-model approach for polarizing surfaces based on stacked meander-line gratings
Abstract
This manuscript reports the design of polarizers consisting of stacks of several meander-line gratings for axial-ratio enhancement. Analysis and design are carried out with analytical equivalent circuits that fully characterize periodic meander-line architectures. The advantage of using the analytical equivalent-circuit approach lies on its accuracy as well as in the better physical insight of the structure's behavior provided by this approach. Extension to the case of oblique incidence is also carried out. Comparisons between results obtained by a commercial software and by the circuit model will evidence the good accuracy of the proposed approach. © Institution of Engineering and Technology.All Rights Reserved.
