The approximation algorithm to the tensor Green's function calculation in the D'Alembert equation for the polarization potential in the circular waveguide is proposed. The tensor Green's function is presented in the sourcewise form as the sum of the Green's function for free space and the regular part caused by reflections from the waveguide walls. The circular waveguide is a circular cylinder with...
The concept of a local phase center is discussed. At the test example, the computation algorithm has been validated by an analytical one. A technique overwhelming some calculus difficulty is presented. An indefiniteness of a local phase center is proved to be not greater than that of a widely used notion of an antenna phase center.
