Exploring the potentials of the multi-modal equivalent circuit approach for stacks of 2-D aperture arrays

Many frequency-selective surface (FSS) structures are based on the use of a single periodic array of slot/apertures in a conducting sheet embedded in a layered medium. However, it is well known that stacking several conducting sheets and breaking the alignment of the stack can bring multiple benefit...
