Analysis of Electromagnetic Performance, Coupling of Couple Nanoholes

Tehran, Iran | Posted on March 10th, 2014

The research presents a new approach to behavior and optical and electromagnetic interaction between two adjacent coupled nanoholes, which eases the analysis and modeling of optical properties of similar nanostructures that are commonly used in nanotechnology.

In this research, the researchers studied strong near-field optical interaction between two nanoholes with sub-wavelength of 100-200 nm2, which were caused by longitude and latitude arrangements on a thin film of gold with a thickness of 100 nm.

Optical properties of plasmonic nanoholes can be analyzed by using equivalent magnetic dipoles through this research. The research also proved that contrary to interaction between nanoparticles where electrical field vector has the dominant role, incident light magnetic field vector plays the dominant role in strong interactions of nanoholes. Therefore, new plans can be proposed to control and engineer optical properties of nanostructures containing nanopores or nanoholes.

The plan also provides a new method to analyze and design nanostructures based on nanoholes with sub-wavelength dimensions. Generally speaking, a new approach to optical and electromagnetic behavior of adjacent coupled nanoholes has been suggested, which eases the analysis and modeling of optical properties of similar nanostructures that are commonly used in nanotechnology.

The research was carried out in form of scientific cooperation between Khajeh Nasir Tousi University of Technology and Iran University of Science and Technology.Results of the research have been published in Optics Express, vol. 21, issue 26, December 2013, pp. 31769-31781.
