The accuracy of Modified Edge Representation in surface-to-line integral reduction of Physical Optics is investigated in diffracted field. This components is compared between two results given by MER line integration and PO surface integration. The stability of diffraction at RB calculated by MER has been examined which depended on the integral path of scatterer's periphery especially closed to reflection...
Equivalent edge currents (EECs) for high frequency diffraction analysis are the intermediate concepts between Ray theory and Wave optics (Physical optics). EEC eliminates the caustic singularities of the ray theory at the cost of additional line integration. The high frequency localization by using the Fresnel zone numbers in stead of the stationary phase method could be applied to EEC and the uniform...
It is investigated about the diffracted field of the accuracy by Modified Edge Representation in surface-to-line integral reduction of Physical Optics. This components is compared between two results, MER line and PO surface integrals. The performance of stability from MER on RSB is confirmed, and this characteristic is shown in this paper.
In this paper, the scattering geometrical optics and line integral of Modified Edge Representation are introduced. The differences between Scattering Geometrical Optics and Modified Edge Representation line integration is discussed in ellipsoid case. The difference term is expressed by mathematical formula.
The Modified Edge Representation is a concept to be used in the integral approximation for computing the surface radiation integrals of diffraction. It applied to the physical optics has remarkable accuracy in the surface-to-line integral reduction even for the curved surface and for sources very close to the scatterer. Geometrical Optics is an approximate high-frequency method for determining wave...
Equivalent Edge Currents (EECs) are widely utilized to asymptotically express the edge diffraction from the periphery of the scatterers, as in the concept suggested by Young. Authors proposed novel EECs based upon the unique concept named as Modified Edge Representation (MER), for surface to line integral reduction of Physical Optics (PO) radiation integrals. MER is based upon not only asymptotic...
