研究目的
To solve the 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.
研究成果
The problem of scattering a plane E-polarized wave on a Van Atta waveguide array located on a circular perfectly conducting cylinder is solved. The solution involves solving an infinite system of linear algebraic equations for the expansion coefficients of the tangent component of the magnetic field vector on the cylinder surface and in the apertures of the radiators.
研究不足
The study assumes that bends in the waveguides do not affect the propagation conditions of electromagnetic waves, which may not account for all real-world complexities.
1：Experimental Design and Method Selection:
The problem is approached using the Lorentz lemma in integral form, reducing the task to solving an integral equation for the magnetic field vector over the entire surface of the cylinder.
2：Sample Selection and Data Sources:
The study focuses on a perfectly-conducting circular cylinder with a Van Atta waveguide array on its surface.
3：List of Experimental Equipment and Materials:
The setup involves plane-parallel multimode waveguides of uniform length connecting radiators in the form of open ends of waveguides.
4：Experimental Procedures and Operational Workflow:
The solution involves solving 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.
5：Data Analysis Methods:
The scattering diagram is analyzed through the geometrical parameters of the structure.
