A detailed parametric study on the stopband characteristics of complementary split ring resonators (CSRRs) based on its length, shape (circular or rectangular), substrate on which it is printed, split gaps, etching on ground plane or substrate or both, single or multiple split rings and periodicity, etc. is done. Such a detailed investigation is not reported till date. This will be useful for p...

In this paper, a simple method to obtain a notch in the ultra-wideband (UWB) bandpass filter is presented. UWB bandpass filter is designed using ground plane aperture technique. To reject the undesired wireless local area network (WLAN) signals, a complementary single split ring resonator (CSSRR) is placed under the coupled lines of the bandpass filter. The CSSRR has flat insertion loss and goo...

In this paper, suppression of mutual coupling is achieved using compact waveguided metamaterials (WG-MTMs) in between elements of a densely packed microstrip array. Both the E-plane internally folded complementary split ring resonator and the H-plane internally folded complementary split ring resonator are employed to reduce the mutual coupling between adjacent elements. Coupling suppression of...

A compact meander-line resonator is proposed in this paper, which could provide negative permittivity with a small unit-towavelength ratio. The meander-line structure is simple to be designed and is convenient to be controlled. Negative index materials (NIM) are realized using units composed of meander lines and split-ring resonators (SRRs), which have simultaneously negative permittivity and p...

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 ...
