Nanowire Antenna Emission

Nano Letters, 2012
We experimentally demonstrate the directional emission of polarized light from single semiconductor nanowires. The directionality of this emission has been directly determined with Fourier microphotoluminescence measurements of vertically oriented InP nanowires.

Spiral antennas and antenna arrays

2005 IEEE Antennas and Propagation Society International Symposium, 2005
The planar square-Archimedean spiral located at the center of a dipole has been demonstrated as a valuable passive antenna element in the upper MM-wave and THz regions between about 100 GHz and 2 THz (Bjarnason, E. et al., Appl. Phys. Lett., vol.85, p.3983, 2004).

BesselBeam Antennas

2021
The capability of controlling the spatial broadening of the radiation moving away from the relevant sources is considered a very attractive feature for a plethora of applications, such as imaging, diagnostic, and wireless power transfer. An important class of ideal solutions of the scalar wave equation that remain confined and do not undergo ...

Large antennas and microwave antennas

2005
Large antennas and microwave antennas, which form the subject of the remaining chapters of this book, are characterized by the property that their useful dimensions are very large compared with the wavelength involved. The word ‘large’ refers to the physical dimensions of the antenna (radio telescopes, for example) compared with which the wavelengths ...

Antenna Analyses: Objects Near Antennas and Microstrip Antennas.

1980
Abstract : In this report the research work encompassed two classes of antenna analyses. One was an investigation of the effects of a nearby object upon an antenna and its performance and the other was a study of the center-fed, circular microstrip antenna.

Multiple antennas: smart antenna systems

2010
Introduction Wireless channels suffer from time-varying impairments such as multipath fading, interference, and noise. Diversity, such as time, frequency, space, polarization, or angle diversity, is typically used to mitigate these impairments. Diversity gain is achieved by receiving independent-fading replicas of the signal.
