Abstract:
An Iranian researcher from Sharif University of Technology succeeded in significantly reducing (a few hundred times) the time required for electromagnetic analysis of graphene-based structures by presenting a novel approximate boundary conditions for magnetic field.

Significant Reduction in Electromagnetic Analysis Time of Graphene-Based Alternate Structures

Tehran, Iran | Posted on January 18th, 2014

The boundary condition can be very important in the analysis of very thin structures, including graphene.

"In this research, we presented an approach for fast analysis of alternate arrays of graphene bands. The analysis of the arrays is very time-consuming through the methods based on Fourier's model. In this article we present a method that can reduce the time required for the analysis of such structures a few hundred times," the researcher said.

The researcher increased the convergent rate of Fourier Modal Method (FMM) in the analysis of arrays consisting of graphene bands. FMM is one of the most common methods in the analysis of optical structures.

Alternate arrays of graphene have applications in the production of various optical devices, including optical sensors, light sorbents, lenses with the ability higher than diffraction limit, and terahertz supermaterials. Obviously, it is mandatory to employ a fast device to analyze such structures to design them.

Latest results of the research showed that the structure could play the role of an element of electrical circuit, and the mentioned element was characterized.

Results of the research have been published in details in Optics Letters, vol. 38, issue 16, 15 August 2013, pp. 3009-3012.
