Inverse Transformation Optics with Realistic Material Parameters

We present a method to generate transformation functions based on a space of achievable material properties. To validate this approach, we consider the range of effective refractive index achievable using silver nanowires in a dielectric background. Given fabrication constraints, we generate a reduced cloaking transformation and confirm its performance using FDTD and FEM simulations. We explore...

Demystifying Material Parameters for Terahertz Electromagnetic Simulation

Two industry-standard electromagnetic modelling software packages, HFSSTM and CST Microwave Studio, are used extensively for modelling arbitrary THz structures. However, with both there are a number of practical issues that relate to how such commercially-available software can be used to give results that are meaningful and accurate. In this paper conventional air-filled metal-pipe rectangular...

Design of electromagnetic cloaks and concentrators using form-invariant coordinate transformations of Maxwell’s equations

The technique of applying form-invariant, spatial coordinate transformations of Maxwell’s equations can facilitate the design of structures with unique electromagnetic or optical functionality. Here, we illustrate the transformation-optical approach in the designs of a square electromagnetic cloak and an omni-directional electromagnetic field concentrator. The transformation equations are descr...

Coordinate transformation formulation of electromagnetic scattering from imperfectly periodic surfaces.

This paper considers the electromagnetic scattering problem of periodically corrugated surface with local imperfection of structural periodicity, and presents a formulation based on the coordinate transformation method (C-method). The C-method is originally developed to analyze the plane-wave scattering from perfectly periodic structures, and uses the pseudo-periodic property of the fields. The...

Image coordinate transformation based on DIV-CURL vector splines

In this paper, we present a vector spline technique for vector field reconstruction. These vector splines are based on an energy minimization functional, which involves the divergence and the rotational fields of the approximated vector. This technique can be used to determine the underlying coordinate transformation in image mapping.
