Dual-Band and Multi-State Polarization Conversion Using aTerahertz Symmetry-Breaking Metadevice
Nanomaterials, 2023 We numerically and experimentally demonstrate a terahertz metadevice consisting of split-ring resonators (SRRs) present within square metallic rings. This device can function as a dual-band polarization converter by breaking the symmetry of SRRs. Under x-

A new characterization of the dual polar graphs [PDF]
Journal of Combinatorial Theory, Series B, 2019 In this paper we give a new characterization of the dual polar graphs, extending the work of Brouwer and Wilbrink on regular near polygons. Also as a consequence of our characterization we confirm a conjecture of the authors on non-bipartite distance-regular graphs with smallest eigenvalue at most $-k/2$, where $k$ is the valency of the distance ...

Dual-Polarized All-Metallic Metagratings for Perfect Anomalous Reflection
, 2020 We theoretically formulate and experimentally demonstrate the design of metagratings (MGs) composed of periodic rectangular grooves in a metallic medium, intended for perfect anomalous reflection. Using mode matching, a semianalytical scheme for analysis
