The diffraction theory of Stratton and Chu is applied to a calculation of the vertical polar diagram and the gain of a parabolic cylindrical antenna. This antenna is fed by a line source having a known energy distribution and polarization. A numerical calculation for a particular profile is carried out, and the results are compared with those obtained ...

Sonic microwave-antenna simulator
IEEE Transactions on Antennas and Propagation, 1986A simulator is described which generates and transmits beams of audible sound energy which are mathematically similar to those generated in a microwave system. The simulator's transmitting elements form a phased array that electronically focuses and steers coherent sonic beams allowing microwave antenna pattern generation to be studied acoustically in ...

Intraoperative Triple Antenna Hepatic Microwave Ablation
American Journal of Roentgenology, 2006Microwave ablation is emerging as a new treatment option for patients with unresectable hepatic malignancies. This two-center study shows the results of a phase 1 clinical trial of patients with known hepatic masses who underwent synchronous triple antenna microwave ablation before elective hepatic resection.Intraoperative microwave ablation was ...

EBG Antenna for Microwave Links Applications
2006 2nd International Conference on Information & Communication Technologies, 2006In this paper we propose an EBG antenna which presents a good candidate for microwave links systems and more specifically for point to point and the point to multipoint applications required directives antennas with a high gain. The design of the antenna is consisting of a waveguide-fed slot antenna on which we add a one dimension EBG resonator ...

Voltage breakdown characteristics of microwave antennas
IRE International Convention Record, 1959At low pressures, antennas are susceptible to voltage breakdown. In the case of missiles, for example, there are indications that very low power is sufficient to initiate and maintain breakdown. Since it is essential that the system performance is not interrupted for high-altitude operation, an experimental investigation has been made to study the ...

Microwave Aperture Antennas and Diffraction Theory*
Journal of the Optical Society of America, 1962Various studies of diffraction of electromagnetic waves motivated by and applied to work on microwave aperture antennas are reviewed in relation to their significance to the study of optics. A critique of the Kirchhoff formula is presented to show the essentially heuristic nature of the formula and its range of applicability.
