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 ...

Hybrid Beamforming for dual-polarized antenna [PDF]
2019 IEEE Wireless Communications and Networking Conference (WCNC), 2019 Recently, dual-polarized antenna has attracted strong attention in Millimeter wave (mmWave) systems. It provides an additional degree-of-freedom in wireless communication, yielding higher throughput. Nowadays, with the development of antenna technology, dual-polarized large scale antenna arrays can be realized inexpensively. However, several challenges
