Improved sensitivity of terahertz label free bio-sensing application through trapped-mode resonances in planar resonators
Improved sensitivity of terahertz label free bio-sensing application through trapped-mode resonances in planar resonators
A design is proposed and investigated exploiting full wave numerical simulation of a dual resonant structure with an aim to sense small amounts of chemical and biochemical materials. The structure is energized with free space radiation in the terahertz regime. Thanks to its asymmetric geometry high quality trapped mode resonances are excited. By selectively loading the structure with only small amounts of probe material, a relatively large shift in the frequency response may be achieved. The concept is demonstrated through simulation, while optimization of the structure and the analyte loading is attempted.

Abstract
A design is proposed and investigated exploiting full wave numerical simulation of a dual resonant structure with an aim to sense small amounts of chemical and biochemical materials. The structure is energized with free space radiation in the terahertz regime. Thanks to its asymmetric geometry high quality trapped mode resonances are excited. By selectively loading the structure with only small amounts of probe material, a relatively large shift in the frequency response may be achieved. The concept is demonstrated through simulation, while optimization of the structure and the analyte loading is attempted.
