Abstract

In this contribution, we present an omega-shaped electromagnetic resonator, which is of potential interest for THz biosensors. A new analytical model for such an inclusion-type is developed, considering the effects of the fringing capacitance. After the development of a proper parametric (analytical and numerical) analysis, we optimize the design in terms of selectivity and sensitivity for the operation of the biosensor at THz frequencies. The obtained biosensor exhibits an higher selectivity and sensitivity compared to similar devices already presented in the literature.
