Analysis of a thin, penetrable, and nonuniformly loaded cylindrical reflector illuminated by a complex line source
(Institution of Engineering and Technology, 2017)A thin, penetrable, and cylindrical reflector is illuminated by the incident field of a complex source point. The scattered field inside the reflector is not considered and its effect is modelled through a thin layer ... 
Analysis of an arbitrary conic section profile and thin dielectric cylindrical reflector illuminated by an Epolarized complex source point beam
(IEEE, 2012)We simulated arbitrary conic section profile and thin layer dielectric reflector using the Method of Analytical Regularization (MAR) techniques. The reflector is assumed to be illuminated by a complex source point type ... 
Analysis of an arbitrary profile reflector antenna having resistivetype surfaceHpolarization case
(IEEE, 20080607)A regularizationbased numerical solution is obtained for arbitraryshape conic section profile reflector antenna in 2D, for the Hpolarization case. New point is that the reflector surface is assumed a resistivetype ... 
Analysis of the ellipticprofile cylindrical reflector with a nonuniform resistivity using the complex source and dualseries approach: Hpolarization case
(Springer, 2013)An ellipticprofile reflector with varying resistivity is analyzed under the illumination by an Hpolarized beam generated by a complexsourcepoint (CSP) feed. The emphasis is done on the focusing ability that is potentially ... 
Comparative evaluation of absorbing boundary conditions using Green's functions for layered media
(Institute of Electrical and Electronics Engineers, 199602)Absorbing boundary conditions are comparatively studied using the Green's functions of the vector and scalar potentials for multilayer geometries and general sources. Since the absorbing boundaries are introduced as ... 
Effect of the offfocus shift of the feed on the radiation characteristics of a 2D parabolic reflector antenna
(IEEE, 2010)The parabolic reflector antennas are widely used in the telecommunication systems and generally have large aperture sizes like 50λ to 80λ and larger. Their reliable fullwave analysis with the conventional Method of Moments ... 
Focusing ability of a microsize graphenebased cylindrical reflector in the THz range illuminated by electromagnetic plane wave
(IEEE, 201607)The scattering of the Hpolarized plane wave by a twodimensional (2D) parabolic reflector made of graphene placed in the free space is simulated by using the Method of Analytical Regularization (MAR) technique. The total ... 
Focusing of THz waves with a microsize parabolic reflector made of graphene in the free space
(Springer International Publishing, 2017)Background: The scattering of H and Epolarized plane waves by a twodimensional (2D) parabolic reflector made of graphene and placed in the free space is studied numerically. Methods: To obtain accurate results we use ... 
Influence of phase function on modeled optical response of nanoparticlelabeled epithelial tissues
(2011)Metal nanoparticles can be functionalized with biomolecules to selectively localize in precancerous tissues and can act as optical contrast enhancers for reflectancebased diagnosis of epithelial precancer. We carry out ... 
Lighting monuments: reflections on outdoor lighting and environmental appraisal
(Elsevier, 200606)For more than 10 years, highlighting urban pattern, revealing the artifacts in our surroundings, and providing relationships among the elements of cities, outdoor lighting practice gained more significance. The following ... 
Modelbased spectral analysis of photon propagation through nanoparticlelabeled epithelial tissues
(SPIE, 2011)Metal nanoparticles can function as optical contrast enhancers for reflectancebased diagnosis of epithelial precancer. We carry out Monte Carlo simulations to model photon propagation through normal tissues, unlabeled ... 
Modeling of spirals with equal dielectric, magnetic, and chiral susceptibilities
(Taylor & Francis Inc., 2008)In this article, we study spiral particles with optimized design parameters, which can make possible the realization of media with equal dielectric, magnetic, and chiral susceptibilities. Two different spiral structures ... 
Object rigidity and reflectivity identification based on motion analysis
(IEEE, 2010)Rigidity and reflectivity are important properties of objects, identifying these properties is a fundamental problem for many computer vision applications like motion and tracking. In this paper, we extend our previous ... 
Offgrid sparse SAR image reconstruction by EMMP algorithm
(IEEE, 2013)A new and robust sparse SAR image reconstruction technique is proposed for offgrid targets in the CS framework. In the proposed approach, basis vectors corresponding to ongrid point reflectors are perturbed on a finer ... 
Radiation characteristics of a 2D parabolic reflector antenna excited by the Hpolarized complex source

Rapid classification of surface reflectance from image velocities
(Springer, Berlin, Heidelberg, 2009)We propose a method for rapidly classifying surface reflectance directly from the output of spatiotemporal filters applied to an image sequence of rotating objects. Using image data from only a single frame, we compute ... 
Rapid inference of object rigidity and reflectance using optic flow
(Springer, Berlin, Heidelberg, 2009)Rigidity and reflectance are key object properties, important in their own rights, and they are key properties that stratify motion reconstruction algorithms. However, the inference of rigidity and reflectance are both ... 
Stage fright: internal reflection as a domain general enabling constraint on the emergence of explicit thought
(Elsevier Ltd, 2018)It has become increasingly clear over the last half century that there are multiple importantchanges in children’s abilities taking place at around age 4. These changes span social, emotional,and cognitive domains. While ...
