Abstract:

Background: The paper reports on typical characteristics of resonant electromagnetic modes propagation through interfaces of a multilayer device.

Methods: Using the transfer matrix method, p-reflectance is analyzed in angular interrogation for a symmetrical cavity performed with left-handed metamaterial layer mediated with GaAs.

Result: An advantage of SPR sensor is demonstrated in terms of optimal performances by controlling thicknesses, refractive indices and dielectric gap layers of the media involved.

Conclusion: The functionality of the proposed design, as a tunable filter, has been also identified.

Keywords: Plasmonic sensor, left-handed material, prism materials, angular sensitivity, sub-wavelength scale, SPR.
