Optical Yagi-Uda nanoantennas
optical nanoantennas Yagi-Uda antennas all-dielectric nanoantennas plasmonics nanoparticles spectral tuning Purcell factor
2012/4/19
Conventional antennas, which are widely employed to transmit radio and TV signals, can be used at optical frequencies as long as they are shrunk to nanometer-size dimensions. Optical nanoantennas made...
Circular Optical Nanoantennas
Circular Optical Nanoantennas entirely analytical theory Fabry-Perot resonator model
2011/8/11
Abstract: An entirely analytical theory is provided for describing the resonance properties of optical nanoantennas made of a stack of homogeneous discs, i.e. circular patch nanoantennas. It consists ...
Diamond particles as nanoantennas for nitrogen-vacancy color centers
Diamond particles nanoantennas nitrogen-vacancy color centers Quantum Physics
