In this paper, for the first time to our knowledge, we investigate the optical bi-stability in a compact parallel array of micro- ring resonators with 5μm radius, induced by optical nonlinearity. Due to the nature of perfect light confinement, resonance and accumulation process in a ring resonator, optical nonlinear effects, even at small optical power of a few milliwatts in this structure are ...

This article presents a software (NMR PROBES) for design NMR probes using closed-forms formulas of the primary and secondary parameters of the shielded split ring [1] and the shielded symmetrical band resonators [2]. These formulas are based on rigorous analysis by finite element method (FEM) [3], [4], method of moment (MoM) [5] and curves fitting techniques. The presented software permits the ...
