Theory of highly directional emission from a single subwavelength aperture surrounded by surface corrugations.
We present a theoretical foundation for the beaming of light displayed by a single subwavelength aperture in an appropriately corrugated metal film [H. J. Lezec, Science 297, 820 (2002)]]. Good agreement is found between calculations and experimental data. We show that beaming is due to the formation of electromagnetic surface resonances and that the beam direction, width, and wavelength at whi...
متن کاملField enhancement in a circular aperture surrounded by a single channel groove.
Numerical analysis of diffraction by a single aperture surrounded by a circular shallow channel in a metallic screen shows the possibility of a 50-fold increase of the electric field intensity inside the central aperture, when compared to the incident field. Detailed analysis of cavity modes and their coupling through surface plasmon wave determine the parameters leading to maximum field enhanc...
متن کاملWideband Cavity-backed Crossed Dipoles for Circular Polarization
Abstract—A novel circularly polarized cavity-backed antenna (CBA) excited by crossed bowtie dipoles is presented in this paper. It is fed by a transition from a microstrip line to doubleslot lines. The crossed dipoles consist of a top-loaded triangular and a filleted rhombic to achieve the required input impedance relations for circularly polarized radiation. After optimization, a simulated 3-d...
متن کاملLight diffraction by a subwavelength circular aperture
Diffraction of normally incident light by a subwavelength circular aperture is calculated analytically. The aperture is opened on a perfectly conducting planar screen with infinitesimal thickness. In our model, the aperture is replaced by uniform magnetic currents and charges. The model allows one to obtain the normalized cross section for the aperture radius up to half of the wavelength, which...
متن کاملRadiation from a Point Charge Moving through a Circular Aperture in a Screen
This paper deals with the problem of diffraction radiation from an electric point charge that moves, at a constant speed, through a circular aperture in a plane screen. The screen is assumed to be electrically perfectly conducting. The problem is reduced to the solution of an integral equation for an unknown field function in the aperture. Low-frequency solutions as well as high-frequency solut...
