A varactor controlled electronically reconfigurable dipole antenna is presented. The property of a stepped impedance resonator is utilized to achieve the resonant frequency of the dipole antenna. By ...

We investigate the properties of finite gold nanocones as optical antennas for enhancing molecular fluorescence. We compute the modification of the excitation rate, spontaneous emission rate, and ...

A dual linearly polarized antenna array with end-fire radiation of the 60-GHz band is proposed by combining two types of magneto-electric dipoles (ME-dipole), which operate in vertical polarization (V ...
