Conference Object Review on the Modified Theory of Physical Optics(Ieee, 2018) Basdemir, Husnu Deniz; Basdemir, Husnu DenizIn this review, modified theory of physical optics approach to the diffraction problem is revisited. The important aspects of the method are explained and steps for the usage of the method are revealed. Also, historical progress of the method is mentioned.Article Citation - WoS: 3Citation - Scopus: 4Po and Ptd Approach To the Diffraction Problem by a Resistive Half-Plane(Taylor & Francis Ltd, 2014) Basdemir, Husnu DenizDiffracted fields from a resistive half-plane were investigated by the method of physical optics (PO) and the physical theory of diffraction. The coefficient of the PO scattering integral was derived for the first time for the resistive half-plane. Uniform fringe field expressions were obtained in terms of the Fresnel functions. The resultant expressions of the fringe fields were plotted and analyzed numerically.Conference Object Method of Total Fields for Diffraction Problems Between Different Media(Ieee, 2019) Basdemir, Husnu DenizIn this present study a new method which gives the scattered field by a canonical structure between two different media is introduced. This method is applied to the half-plane with soft boundary condition. The fields are examined numerically. Thus, numerical analysis showed that the proposed method is suitable for these kinds of problems.Article Citation - WoS: 4Citation - Scopus: 4An Analytical Solution for the Plane Wave Diffraction by a Resistive Half-Plane Residing at the Interface of Left and Right Handed Media(Elsevier Gmbh, 2019) Basdemir, Husnu DenizThe diffraction of waves by a resistive half-plane lying on the interface of left and right handed media is investigated in this study. Because of the anomalous refraction property of left handed media, shadow boundary shifts toward to the lower surface of the half-plane. In order to obtain the shifted boundary, diffracted waves are divided to subfields. Thus, obtained diffracted waves compensates the deficiency of geometries optics fields at the transition regions. The uniform version of waves is obtained by using the uniform theory of diffraction. The wave behaviors are examined numerically.Article Citation - WoS: 12Citation - Scopus: 12Scattering of Waves by a Perfectly Conducting Wedge Residing at the Interface Between Two Isorefractive Media(Ieee-inst Electrical Electronics Engineers inc, 2016) Basdemir, Husnu DenizScattered field by a wedge that is surrounded by isorefractive media is analyzed. A series-based method is introduced and applied to the wedge problem with soft boundary condition. The fields are examined numerically. The numerical results show that the proposed method is suitable for analysis of these kinds of problems.Article Citation - WoS: 3Citation - Scopus: 3Scattering of Inhomogeneous Plane Waves by a Truncated Cylindrical Cap(Taylor & Francis Ltd, 2015) Basdemir, Husnu DenizScattered fields of the inhomogeneous plane waves from a truncated cylindrical cap are obtained. Also the uniform diffracted fields are performed in terms of the Fresnel functions. Reflected and diffracted fields are obtained by using the physical optics and the geometrical theory of diffraction methods, respectively. All the mentioned results are plotted numerically for various numerical parameters.
