Novel Microwave Microfluidic Sensor Using a Microstrip Split-Ring Resonator

High resolution microwave microstrip resonator for sensing applications

“…The label-free potential of the split-ring resonator for detection applications was shown by Lee et al for biomolecule detection [16]. The dielectric permittivity of a liquid was studied in a microfluidic structure using planar microwave resonators [17,18]. The planar microwave structures have recently shown promising potential in gas sensing as well.…”

Simulation Based Comparative Analysis of Resonant Frequency for Tunable Split Ring Resonator in Different Configurations

“…The dimensions of metallic cylindrical cavity and other optimized parameters [9], [15], [5] used for simulations are shown in Table 1. The material selected for cavity and SRs are Aluminum and Copper respectively [17].…”

“…These designs primarily employ cavity perturbation methods to sense shift in ƒ r and change in Q when small amount of homogeneous solution of liquids is placed between the capacitive gap/split. These two parameters depend upon the dielectric constant of the resonator [5].…”

Spectral signature barcodes based on S-shaped Split Ring Resonators (S-SRRs)

“…In this case, where the functionality is based on particle resonance (rather than on impedance and dispersion engineering), the lines are usually referred to as transmission lines with metamaterial loading [3]. These structures have been applied to the design of planar bandstop and notch filters [4,5], multiband printed dipole and monopole antennas [6][7][8], commonmode suppressed differential lines and filters [9,10], microwave sensors [11][12][13][14][15][16][17][18], and radiofrequency barcodes [19][20][21], among others.…”
