Paper Abstract

Designing metamaterials to possess extreme index values requires near resonant properties which, in turn, leads to these properties over diminishing bandwidths. Recent studies have shown that some bandwidth control might be possible by exploiting metamaterial substrates. We have demonstrated the concept in our design, and investigated the trade-offs between substrate structure, bandwidth extension and increase in losses. Loss management can be controlled by choice of metamaterial elements and replacement of metal by semiconductors. This also has the added advantage of some degree of tunability.
