Terahertz (THz) spectral band, from about 0.1 to 15 THz, is one of the least explored yet most technologically transformative spectral regions. A large number of interesting scientific phenomena are only accessible by THz photons and THz radiation also finds a lot of practical applications. However, for a long time, THz scientific research and technological development is greatly limited due to the...
In this paper, we consider plasmonic nanoantennas with different elliptical metal rods embedded in a two-arm grating. Elliptical metal rods support dipolar localized plasmon resonance with a localized plasmon resonance frequency that is affected with different metal materials. We discuss the properties and parameters of different elliptical metal rods using finite-difference time-domain method in...
