β¦ Synopsis
In this article the theoretical analysis concerning photoconducting antennas is made with the use of time-resol¨ed Maxwell equations associated with a drift diffusion model for photoconductor beha¨ior. This method will be applied to the study of particular antennas in order to see the influence of the electrodes on their response and therefore to predict the influence of the photoconductor en¨ironment on the radiated field.

If the antenna factor is defined as the ratio of incident electric field strength to the output voltage with zero reflection at the load, relative measurement of the antenna factor can be carried out using a reference antenna with a known antenna factor. In this study, an antenna factor of a log dip
Seven different optimized conformers of Ξ±-fluoroglycine (H 2 NCHFCOOH) were obtained from ab initio calculations. Some of these conformers are exceptionally stable compared to similar conformers of glycine. Conformers in which the lone pair of electrons on the nitrogen atom are antiperiplanar to the

The angle of inclination is varied from 0 to 30Β°, with dc magnetic field poHo of 0.35 to 0.4 Wb/m2. Thus, from
The complex antenna factor (CAF) of a dipole antenna with a balun is evaluated by calibrating the S parameters of the balun and calculating the effective length of the antenna element in the frequency range of 600 MHz to 2 GHz. The result is compared with that of the conventional three-antenna metho
