Electronic components design

5030080

In this project, a dual-band Patch antenna is simulated using CST.

Patch antenna design using CST

5030032

Maxwell lens is a peculiar device. It focuses the rays emanating from the lens rim to the exact opposite side.
We want to verify this behaviour using the electromagnetic module of Comsol.

Maxwell Lens full-wave simulation using Comsol

5029993

A Luneburg Lens is a spherical graded index lens that can create directive beams out of a point source placed at the lens circumference.
In this example, we use Matlab to solve the ray tracing equations (Hamilton equations) inside this nonhomogeneous medium to track the rays as they propagate from the point source on the lens rim.

Design of polarization splitting devices with ideal transmission and anisotropy considerations

OSA-Josa B

In this paper, we introduce the generalized design of nonmagnetic homogeneous polarization splitting devices (polarization deflector/lateral shifter) based on linear area-preserving transformations for an arbitrary incident angle. Also, by employing the Brewster angle condition, we derive a quadratic equation for principal values of the permittivity tensor that leads to the reflectionless splitting of two orthogonal polarizations for a normally impinging wave.

Transformation optics for perfect two-dimensional non-magnetic all-mode waveguide couplers

OSA-Optical Materials Express

Here, we demonstrate that transformation optics can be used to produce 2-D non-magnetic waveguide couplers with no reflections. Our approach consists of using a scaling function for reflection suppression and introducing an auxiliary function in the transformation optics formulation to achieve a non-magnetic medium for coupling the TM polarization.

Reflectionless design of a nonmagnetic homogeneous optical waveguide coupler based on transformation

OSA-JOSA B

We propose a reflectionless design of an optical waveguide coupler that is nonmagnetic and homogeneous. The coupler is designed using the linear coordinate transformation of triangles. The common problem of reflections from the boundaries of a nonmagnetic coupler is remedied by analytically specifying the common vertex of triangles. The device performs ideal transmission. We employ effective medium theory to demonstrate the realizability of the device.

Elliptical Generalized Maxwell Fish-Eye Lens using Conformal Mapping

IOP-New Journal of Physics

A circular graded index lens is conformally transformed to an elliptical shape using a closed-form transformation. The proposed transformation is then employed to compress a Maxwell fish-eye and its generalized version. Since the transformation is conformal, the electromagnetic properties of the device are perfectly preserved after the transformation with fully isotropic and dielectric-only materials.
