#### Comparison of beam profiles from analytic solution and computational models

(2014-01)

In this thesis, we have compared the receiver plane beam profiles by computing the Huygens-Fresnel integral as convolution integral and Fourier integral operator and the results obtained from analytic derivation. The ...

#### Diffraction of the packet-like and nondiffracting propagating beams by an obstacle in the atmosphere

(2008-06-11)

This thesis takes two different solutions of homogenous wave equation into consideration. These solutions are named as packet-like solution and non-diffracting beam.First of all the propagation of these waves in the ...

#### Average intensity and spreading of an elegant Hermite-Gaussian beam in turbulent atmosphere

(Optical Soc Amer, 2009-06-22)

The propagation of an elegant Hermite-Gaussian beam (EHGB) in turbulent atmosphere is investigated. Analytical propagation formulae for the average intensity and effective beam size of an EHGB in turbulent atmosphere are ...

#### Scattering of a line source by a cylindrical parabolic impedance surface

(Optical Soc Amer, 2008-07)

The scattering of the radiated fields of a line source by a cylindrical parabolic reflector, which has impedance boundary conditions on its surface, is obtained by using the surface integrals of the modified theory of ...

#### 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 ...

#### Diffraction of plane waves by a black wedge

(Elsevier Science, 2010-02)

The scattering of plane waves by a black wedge is examined. Two methods are considered for the solution of the problem. A closed-form series solution is derived by performing the technique of the separation of variables ...

#### Closed form series solution of the diffraction problem of plane waves by an impedance half-plane

(IOP Publishing Ltd, 2009-04)

The scattering problem of plane waves by an impedance half-plane is solved by using the method of separation of variables, and a closed form series expression, which separately reduces to the cases of soft and hard ...

#### MTPO based potential function of the boundary diffraction wave theory

(Elsevier Science, 2008-09)

A novel potential function is introduced by using the modified theory of physical optics integrals for a perfectly conducting half-plane. The function is valid for arbitrary aspects of observation. The line integration of ...

#### The effect of impedance boundary conditions on the potential function of the boundary diffraction wave theory

(Elsevier Science, 2008-01-01)

A novel potential function of the boundary diffraction wave theory is obtained for the impedance surfaces by the asymptotic reduction of the modified theory of physical integrals. The function is expressed in terms of the ...

#### Partially coherent elegant Hermite-Gaussian beams

(Springer, 2010-09)

Elegant Hermite-Gaussian beams (EHGBs) are extended to the partially coherent case. An explicit and analytical formula is derived for the cross-spectral density of a partially coherent EHGB propagating through an aligned ...
