This paper presents construction of a composite right/left-handed (CRLH) transmission line (TL) based bandpass filter using microstrip parallel coupled lines and hairpin lines. For getting high coupling in comparison to conventional edge coupled microstrip line, the floating slot on the ground plane is used. Two configuration named as SOS (short-open-short) the OSO (open-short-open) model are s...

In this paper, we consider large non-Gaussianity generated after D-term inflation in the case that the adiabatic curvature perturbation produced is dominated by a right-handed (RH) sneutrino curvaton. The cosmic string problem can also be evaded with around 10% contribution to the CMB power spectrum and the spectral index ns ≃ 1. The non-Gaussianity produced can be as large as 10 < fNL < 100 fo...

Parallel (P) and antiparallel (AP) configurations are widely applied in magnetic heterostructures have significant impacts on the spin-wave transmission magnonic devices. In present study, a theoretical investigation was conducted into of exchange-dominated spin waves with nanoscale wavelengths type heterostructure including two media, which magnetization state can be set to P configuration by ...

A new unit cell composite right/left-handed (CRLH) metamaterial using microstrip technology with coupled line is proposed. It is simple and has a small size. The proposed unit cell can be designed in several frequency bands based on its geometrical parameters. The transition from LH to RH shows the balanced condition without the presence of stop band. Two designs for two different frequency ban...

Using composite right-left handed (CRLH) transmission line concept, a novel miniaturized dual notch band filter (DNBF) is proposed. The suggested DNBF consists of an interdigital transmission line (ITL), split ring resonators (SRRs) and complementary split ring resonators (CSRRs). Since the resonance frequency of the SRRs and CSRRs are quite independent of each other, the dual notch bands of th...
