[IEEE 2019 Radiation and Scattering of Electromagnetic Waves (RSEMW) - Divnomorskoe, Russia (2019.6.24-2019.6.28)] 2019 Radiation and Scattering of Electromagnetic Waves (RSEMW) - Diffraction of a Plane E-polarized Wave on Waveguide Van Atta Array, Placed on the Surface of PEC Cylinder
摘要： The two-dimensional problem of the diffraction of a plane E-polarized wave on a Van Atta waveguide array located on the surface of a perfectly-conducting circular cylinder is solved. The radiators in the form of open ends of waveguides are connected by plane-parallel multimode waveguides of uniform length. The task is reduced to solving an integral equation for the magnetic field vector over the entire surface of the cylinder, which is reduced to an infinite system of linear algebraic equations for the coefficients of the expansion of the magnetic field vector for a complex Fourier series in azimuthal harmonics. The solution of the equation was received strictly and approximately. An expression for the scattering diagram is obtained, represented through the geometrical parameters of the structure.

摘要： The possibility of widening the backscattering pattern (monostatic RCS pattern) of the Van Atta array with changing cylinder radius and array parameters has been studied. Assumed that waveguides are single-mode, and coupling between array radiators occurs through waveguides only. Integral equations obtained in explicit form for tangential component of the electric ?eld intensity in the array elements apertures. Analysis of array RCS performed with di?erent number of array elements pairs N, cylinder radius, aperture size, array spacing, and waveguides lengths.
