Radiation patterns of paraboloids

, 1942
This report contains the results of a study of various methods of exciting paraboloids, made in an effort to obtain methods which would give usable radiation patterns and at the same time permit wobbling the beam for split-beam direction finding. The curves attached to this report give representative radiation patterns and much of the information ...

Optical Vivaldi Antenna Array for Solar Energy Harvesting

Advanced Electromagnetics, 2023
In this paper, we try to find the best solution for our energy harvesting application by designing an efficient optical antenna which receives the solar radiation and converts it from AC to DC by integrating a rectifier.

Evaluation of Kaiser Function-Based Linear Array Performance in Suppressing SLL and Its Experimental Approach

IEEE Access
The power-weighted distribution method is used to satisfy radiation pattern requirements at a certain targeted sidelobe level (SLL) suppression. This article reports a detailed discussion of theoretical and experimental approaches for the application of ...

Theory and applications of toroidal moments in electrodynamics: their emergence, characteristics, and technological relevance

Nanophotonics, 2018
Dipole selection rules underpin much of our understanding in characterization of matter and its interaction with external radiation. However, there are several examples where these selection rules simply break down, for which a more sophisticated ...

Algorithm for Assessing the Characteristics of a Waveguide Slot Antenna Array when Changing Antenna Element Phasing

Известия высших учебных заведений России: Радиоэлектроника
Introduction. When operating antennas in various radio-electronic systems, the influence of phase shifter (PS) failures on the characteristics of phased array antennas, waveguide-slot phased array antennas (WSPAA) in particular, should be taken into ...

ABOUT DETECTION AND RESOLUTION OF LOW-CONTRAST SEDENTARY RADAR TARGETS THAT ARE WITHIN A RESOLUTION ELEMENT

Научный вестник МГТУ ГА, 2016
It is proposed to use the full polarization mode scanning for the detection of weak-contrast targets against the background of the underlying sheets, as well as the construction of space-loop polarization targets for the case of incoherent reflections ...
