Linear Polarization Animation

Uniform plane wave traveling in the +z direction. The x and y component of the electric fields are in phase thus the polarization of the electric field is constant over all space (linearly polarized).

Left Hand Elliptical Polarization (LHEP) Animation

Uniform plane wave traveling in the +z direction. The x and y component of the electric fields have a phase shift with results in a elliptically rotating polarization in the left hand direction.

Radiation from a Circularly Tapered Dielectric Waveguide

Finite-difference time-domain (FDTD) simulation of a dielectric waveguide terminated with a circular tapering. The dielectric permittivity of the waveguide is 2.2 and air is the ambient medium. Such antennas are developed for ground penetrating technology (GPR) technology to reduce the footprint of the antenna. Also see below:Oblique Plane Wave Reflection From Half SpaceRadiation from a… Continue reading Radiation from a Circularly Tapered Dielectric Waveguide

Dipole Antenna Radiation

Finite-difference time-domain (FDTD) simulation of a 2 wavelengths long dipole antenna at 400 MHz in free space. The radiation pattern is very different than that of the traditional half-wavelength dipole antenna. Nulls in the broadside and endpoints are clearly visible Dish Antenna Animation (Parabolic reflector) var _gaq = _gaq || []; _gaq.push([‘_setAccount’, ‘UA-24872537-1’]); _gaq.push([‘_trackPageview’]); (function()… Continue reading Dipole Antenna Radiation
