#### Edge-dislocation waves in the diffraction process by an impedance half-plane

(Optical Soc Amer, 2007-02)

Edge-dislocation waves, created in the diffraction of plane waves by an impedance half-plane, are examined by the method of modified theory of physical optics. The integrals, obtained by a related technique, are decomposed ...

#### Diffraction of electromagnetic waves by impedance slits and strips

(2008-06-11)

In this thesis, diffraction process of electromagnetic waves by strips and slits will be examined by using the methods of the physical optics (PO) and modified theory of physical optics (MTPO) that have impedance boundary ...

#### GTD diffraction coefficient for higher order edge diffracted fields

(2005-06)

Diffraction is the change in the direction of a wave at the edges of the objects. Multiple diffraction occurs when there are two ör more edges in öne ör more objects in same geometry. If there are öne ör more interaction ...

#### Wedge diffraction in terms of the method of physical optics

(IEICE-INTS Electronics Express, 2009-01-10)

The method of physical optics is extended for wedge diffraction. The classical integral of physical optics is taken into account for the diffraction problem of plane waves by a conducting half-plane. The integral is ...

#### Young-Kirchhoff-Rubinowicz theory of diffraction in the light of Sommerfeld's solution

(Optical Soc Amer, 2008-11)

Kirchhoff's theory of diffraction is derived by transforming the exact solution of Sommerfeld into surface integrals for the half-plane problem. It is shown that the exact solution directly yields the integral theorem of ...

#### Diffraction of homogeneous and inhomogeneous plane waves by a planar junction between perfectly conducting and impedance half-planes

(Optical Soc Amer, 2007-01)

The problem of diffraction of homogeneous and inhomogeneous plane waves at the discontinuity formed by perfectly conducting and impedance half-planes is examined by the method of modified theory of physical optics (MTPO). ...

#### The theory of the boundary diffraction wave for wedge diffraction

(Taylor&Francis Inc, 2008)

A new potential function, line integration which gives the edge diffracted fields, is constructed for wedge diffraction by using the method of modified theory of physical optics. The surface integrals are transformed into ...

#### Modified diffraction theory of Kirchhoff

(Optical Soc Amer, 2008-08)

The diffraction theory of Kirchhoff is reinterpreted and a new form of a surface diffraction integral is developed by using the axioms of the modified theory of physical optics, which leads to the exact scattered fields ...

#### Physical optics theory for the scattering of waves by an impedance strip

(Elsevier Science Bv, 2011-04-01)

The physical optics integral of the scattered waves by an impedance strip is derived by using the modified theory of physical optics. The surface currents of the physical optics integral, which was introduced for the ...

#### Effect of the shadow geometry in wedge diffraction

(Optical Soc Amer, 2009-09-01)

The surface integrals of the modified theory of physical optics are divided into two parts for diffraction by a wedge. Each integral represents the incident or reflected field scattered by one of the faces of the wedge. ...
