High frequency structure simulator (HFSS) electrical field simulation results of the bare resonator. (a) The bare geometry of the sensor, (b) the electrical field simulation at the surface of the resonator parallel to the sensor plane, (c) the electrical field simulation perpendicular to the sensor plane and along the ring structure, (d) the electrical field simulation perpendicular to the sensor plane and along the sensitive region of the sensor, (e) HFSS simulation results compared with experimental S21 parameters gathered from testing the resonator alone and with the microfluidic chip assembled. (f) HFSS depiction of the sensor geometry and its entirety.
