#### Smart radome improves reflector antenna directivity

(IEEE, 1997)

A numerical optimization procedure is applied to two dimensional model of cylindrical reflector antenna arbitrarily located inside a circular cylindrical dielectric radome. If the radome thickness has been optimized, then ...

#### Test of accuracy of the generalized boundary conditions in the scattering by thin dielectric strips

(IEEE, 2014-05)

The two-dimensional (2D) scattering of the E and H-polarized plane electromagnetic waves by a free-standing thinner than the wavelength dielectric strip is considered numerically. Two methods are compared: singular integral ...

#### Resonance lens antenna analysis for MM-wave applications

(IEEE, 2004-06)

We report what is to our knowledge the first accurate theoretical investigation of the electromagnetic behavior of 2-D elliptical lenses of finite wavelength-scale size. The role of internal resonances in the focal domain ...

#### Analysis of circular reflectors by complex source-dual series approach

(IEEE, 1993-06-07)

In the present paper, two dimensional circular reflector antennas are analyzed by a rigorous analytical-numerical technique for both E and H polarization cases. The method is used in combination with the complex source ...

#### Wave scattering by one and many thin material strips: singular integral equations, Meshless Nystrom discretization, and periodicity caused resonances

(IEEE, 2014)

We consider the medial-line singular-integral equation technique for the analysis of the scattering by multiple thin material strips. Their discretization is performed using the Nystrom-type scheme that guarantees convergence. ...

#### Fast integral equation techniques for propagation problems

(IEEE, 2004-09)

In this paper, the Method of Moments (MoM) solution is achieved for scattering problems by using the stationary Spectrally Accelerated Forward-Backward method (FBSA) and the non-stationary Spectrally Accelerated BiConjugate ...

#### Numerical diffraction synthesis of 2-D quasioptical power splitter

(IEEE, 2007-06)

A new diffraction synthesis method is proposed for computing quasioptical 2-D reflector beam splitters in the E-polarization case. It is a combination of a numerical gradient (NG) optimization and an efficient analysis ...

#### Microcavity lasers on polymer materials: Boundary integral equation modeling and experiments

(IEEE, 2015-04)

We consider the modeling and experiments with polymer dye-doped lasers shaped as thin flat cavities, allowing one to consider them as two-dimensional (2-D) active cavities. We focus our modeling on the H-polarized ...

#### Numerical modeling of electromagnetic scattering by perfectly conducting surfaces of revolution

(IEEE, 2008-06-07)

The integro-differential equation (IDE) of a three-dimensional (3-D) electromagnetic excitation problem of unclosed surfaces is numerically treated by means of the novel direct solver. © 2008 IEEE.

#### Integral-equation study of ray effects and natural-mode resonances in a 2-D dielectric prism

(IEEE, 2015)

We analyze the interplay of two different types of electromagnetic behavior demonstrated by a 2-D dielectric prism: Geometrical Optics and resonance. As it is shown, the first is responsible, for instance, for enhanced ...
