✦ Synopsis

experiment. It has been found that a transmission zero arises at higher frequencies. The origin of this transmission zero has been interpreted and accounted for in the model by introducing an extra inductance. We have also shown that OCSRRs exhibit higher order resonance frequencies, that correspond to even or odd modes of OCSRR excitation. From this analysis, we have inferred the strategy for resonance suppression (by means of properly allocated metallic strip and vias connecting the different ground plane regions), which has been validated through electromagnetic simulation. Finally, we have highlighted prospective applications of OCSRRs in microwave engineering. OCSRRs are the open version of CSRRs, in the same form that OSRRs are the open version of SRRs. With this new particle, we enhance the design capabilities of microwave circuits and metamaterialinspired structures on the basis of resonant elements.

## Abstract In this article, it is demonstrated that metamaterial transmission lines implemented by means of complementary split rings resonators are useful for the design of planar microwave components with small dimensions and broad operational bandwidths. These characteristics are achieved thank

Two types of excitations (surface and bulk) are responsible for the main features of photoabsorption in free Ar clusters between the 244 and 246 eV. Both the oscillator strength for the 2p ~ 4s transition and its energy in the bulk are higher for the solid than for a free Ar atom or the Ar atoms at
