The abstract, sentence by sentence
In this article, we propose and numerically analyze an all dielectric biaxial metamaterial [ADBM] constructed by multilayer pattering of a sub-wavelength ridge array of Silicon and a flat SiO2 layer. The proposed ADBM can support Dyakonov Surface Waves [DSWs] with infinite propagation length which can propagate in a wide angular domain. Though natural uniaxial and biaxial materials and also nanowire all dielectric metamaterials can also support DSWs, the angular existence domain [AED] is limited to a very narrow range. Our proposed ADBM can support can overcome this limitation and it can achieve higher AED than any all dielectric structures reported in literature till date. Our proposed ADBM can be easily fabricated by the current fabrication technology. Due to its lossless nature, it may find substantial applications in optical sensing, optical interconnects, wave-guiding, solar energy harvesting etc.
