Visualizing radiation patterns of antennas

IEEE Computer Graphics and Applications, 1990
An efficient computer graphics tool for investigating the radiation patterns of antennas as functions of their design parameters is presented. Radiation patterns (or the magnitudes of field distributions) of antennas are treated as three-dimensional surfaces, since the magnitudes of the far-field distributions are functions of polar and azimuthal ...

Synthesis of a slot radiator with a given radiation pattern

Journal of Communications Technology and Electronics, 2009
Synthesis of a slot cylindrical radiator with a given radiation pattern is studied. For a Gaussian pattern, the phenomenon of superdirectivity is analyzed and the parameters of the radiator providing for the optimal spread in the orders of the amplitudes of the currents on slots are estimated.

Angular radiation pattern of Smith-Purcell radiation

Journal of the Optical Society of America B, 1984
The power radiation pattern of Smith–Purcell radiation is measured at various latitudes and azimuth angles relative to the electron beam. The experimental data are used to evaluate the various models and the physical mechanisms previously suggested to describe Smith–Purcell radiation.

Pattern Discovery in Internet Background Radiation

IEEE Transactions on Big Data, 2019
Internet Background Radiation (IBR) is observed in empty network address spaces. No traffic should arrive there, but it does in overwhelming quantities, gathering evidences of attacks, malwares and misconfigurations. The study of IBR helps to detect spreading network problems, common vulnerabilities and attack trends.
