Modeling and simulation of dielectric whispering gallery mode sensor using finite element method at THz frequency

Sensors based on the phenomena of Whispering Gallery Modes have the potential to detect analytes with high sensitivity. The design and optimization of Whispering Gallery Mode Resonator (WGMR) sensors in the THz regime can be modelled using computer simulations before fabrication and experimentation through Finite Element Analysis. We present modelling attempt and simulation results of a ring shaped WGMR along with the analyte molecule 'BSA'. These theoretical results can be used to study and obtain parameters to fabricate optimized devices which can yield results for sensing unlabeled analytes with low concentration and high specificity.
