“…Since the length of a semiinfinite edge tends to infinity, the edge signal scattered value in these areas also tends to infinity. Solution [Klinkenbusch, 2005] is shown in Figure 2 [Klinkenbusch, 2005;Vesnik, 2011].…”

“…Plane angular sector problem is considered in many other sources (see, for instance, Albani [2007] and Lyalinov and Zhu [2012]). In paper [Vesnik, 2011] solution of the same problem is constructed with use of three heuristic approaches: PO, equivalent edge currents method (EECM), and modified EECM (MEECM). In order to verify the obtained heuristic formulas graphs from Klinkenbusch [2005] were used.…”

Different heuristic approaches, such as physical optics method, method of equivalent edge currents, and newly developed modified method of equivalent edge currents are exemplified in a problem of electromagnetic diffraction by a plane angular sector. Comparing with rigorous results has shown that for the problem of electromagnetic diffraction by polyhedrons physical optics method can lead to serious mistakes, method of equivalent edge currents gives a qualitatively correct solution and modified solution by equivalent edge currents method is the most close to a rigorous one. Results of this work can be extended to many scientific and engineering applications in various fields of physics and technology.
