Band structure engineered layered metals for low-loss plasmonics
Plasmonics currently faces the problem of seemingly inevitable optical losses occurring in the metallic components that challenges the implementation of essentially any application. In this work, we show that Ohmic losses are reduced in certain layered metals, such as the transition metal dichalcogenide TaS2, due to an extraordinarily small density of states for scattering in the near-IR origin...
متن کاملLow insertion loss RF MEMS Switch with Crab-leg structure for Ku-band application
Abstract In this paper we present design and analysis of RF MEMS switches with crab-leg connection beam structures. The mechanical characteristics of switch including pull down voltage, hysteresis analysis and capacitance between beam and center conductor are studied. RF characterization of the switch including insertion loss, return loss and isolation are also investigated. Measurement results...
متن کاملGiant colloidal silver crystals for low-loss linear and nonlinear plasmonics
The development of ultrasmooth, macroscopic-sized silver (Ag) crystals exhibiting reduced losses is critical to fully characterize the ultimate performance of Ag as a plasmonic material, and to enable cascaded and integrated plasmonic devices. Here we demonstrate the growth of single-crystal Ag plates with millimetre lateral sizes for linear and nonlinear plasmonic applications. Using these Ag ...
متن کاملFully integrated low-loss band-pass filters for wireless applications
Abstract Fully integrated low insertion loss micromachined band-pass filters are designed and fabricated on the silicon substrate (ρ = 10–20 cm, εr = 11.9) for UHF applications. Filters are made of silver, which has the highest conductivity of all metals, to minimize the ohmic loss. A detailed analysis for realizing low insertion loss and high out-of-band rejection filters using elliptic magnit...
متن کاملRadial band structure of electrons in liquid metals.
The electronic band structure of a liquid metal was investigated by measuring precisely the evolution of angle-resolved photoelectron spectra during the melting of a Pb monolayer on a Si(111) surface. We found that the liquid monolayer exhibits a free-electron-like band and it undergoes a coherent radial scattering, imposed by the radial correlation of constituent atoms, to form a characteristi...
