Novel interpretation of physical optics errors, fictitious penetrating rays and corrections by hybrid use of PO and AFIM
T. Shijo,Makoto Ando +1 more
TL;DR: In this paper, a novel interpretation of physical optics (PO) is discussed and two error factors are identified as error factors, that is, errors in diffraction coefficients and fictitious penetrating rays.

Equivalence of physical optics and aperture field integration method for reflectors approximated by polyhedra
TL;DR: In this article, the equivalence of physical optics (PO) and the aperture field integration method (AFIM) in the full 360/spl deg/ angular region of reflector antennas is discussed from two viewpoints.

Spherical wave strut blockage in high gain reflector antennas
TL;DR: In this article, the spherical wave blockage (SWB) of the struts is considered and the interference of the primary field with such structures may create a rather extended masking of the reflector surface when the strut diameter is large in terms of a wavelength.

A comparison between GO/aperture-field and physical-optics methods of offset reflectors
TL;DR: In this paper, it was shown that for offset parabolic reflectors and for feeds located at the focal point, the predicted far field patterns (amplitude) by the GO/aperture field method will always be symmetric even in the offset plane.
Journal ArticleDOI
Equivalence of surface current and aperture field integrations for reflector antennas
TL;DR: In this paper, the extinction theorem was used to prove that the fields of reflector antennas determined by integration of the current on the illuminated surface of the reflector are identical to the fields determined by aperture field integration with the Kottler-Franz formulas over any surface S = a.

Comparison of induced current and aperture field integrations for an offset parabolic reflector
H. Matsuura,K. Hongo +1 more
TL;DR: In this paper, the authors compared the fields predicted by integration of the physical optics induced currents on the reflector and the geometrical optics aperture fields (AFM) on the surface that caps the reflectors for offset parabolic reflectors.
Proceedings ArticleDOI
Uniform diffraction coefficients of physical optics for impedance surfaces
TL;DR: In this article, uniform diffraction coefficients of physical optics for impedance surfaces are derived, and accuracy is checked, revealing that PO has no polarization conversion at SB/RB geometrical optics boundaries and this fact is numerically checked.
