The split ring resonator was a microstructure design featured in the paper by Pendry et al in 1999 called, "Magnetism from Conductors and Enhanced Nonlinear Phenomena". The dimensions of antenna are calculated to work at 5 GHz with the programmed formula (Table 1 ). Numerical simulation demonstrates that the resonating frequency and quality factor is dependent on the variation of dielectric constant and loss tangent, making it a potential structure for dielectric measurement. The resonance frequency ( {f}_ {0}) of the triple hexagonal split-ring resonators can be expressed by using the general equation [ 48 ]: f_ {0} = \frac {1} { {2\pi \sqrt {L_ { { {\text {eq}}}} C_ { { {\text {eq}}}} } }} (1) where Leq and Ceq represent the equivalent inductance and capacitance of the complete structure.

Activity points. 2 Front view of the proposed antenna Full size image [] In particular, there is a critical need for a survey of different mechanical properties created by kirigami cutting and their broad application appeals. We know that the lumped equivalent circuit of the SRR is an LC circuit. An analytical model is developed for the charge and potential distributions of the fundamental mode of three-dimensional (3D) singly split ring resonators (SRRs) with square cross section, which nowadays can be conveniently fabricated by additive manufacturing techniques. Silicon photonic (SiP) evanescent-field biosensors aim to combine the information-rich readouts offered by lab-scale diagnostics, at a significantly lower cost, and with the portability and rapid time to result offered by paper-based assays.
