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.
