In this paper, we propose and research a novel miniaturized composite right/left handed transmission line (CRLH TL) cell based on revised complementary split ring resonators (CSRRs) for the first time. Novel CRLH TL cell is demonstrated with lower transmission and reflection zeros from electrical and electromagnetic (EM) simulation results. Negative refractive index of CRLH effect is successful...

The models base on SU(3)C ⊗SU(3)L⊗U(1)X gauge group contain new Higgs bosons and one of them is the SM-like Higgs boson. In the context of 3-3-1 model with righthanded(RH) neutrinos, we study the Higgsstrahlung process ee → ZH and calculate the cross section of this process at leading order. It is shown that the new heavy gauge boson ZH predicted by this model can generate significant contribut...

Supersymmetric thermal leptogenesis with a hierarchical right-handed neutrino mass spectrum requires the mass of the lightest right-handed neutrino to be heavier than about 109 GeV. This is in conflict with the upper bound on the reheating temperature which is found by imposing that the gravitinos generated during the reheating stage after inflation do not jeopardize successful nucleosynthesis....

We study the propagation of quasidiscrete microwave solitons in a nonlinear left-handed coplanar waveguide coupled with split-ring resonators. By considering the relevant transmission line analog, we derive a nonlinear lattice model which is studied analytically by means of a quasidiscrete approximation. We derive a nonlinear Schrödinger equation, and find that the system supports bright envelo...

Based on the parity violation in Standard model, we study the dependence of lifetime on the helicity of an initial-state fermion in weak interactions. It is pointed out that if the initial fermions in the decays are longitudinally polarized, then the decay lifetime of left-handed polarized fermions is different from that of right-handed polarized fermions in flight with a same velocity in a sam...

We consider an extension of the Standard Model with three right-handed (RH) neutrinos and a Dirac pair extra sterile neutrinos, odd under discrete $Z_2$ symmetry, in order to have left-right symmetry neutrino content obtain tiny masses from latter ones only. Our working hypothesis is that heavy RH do not influence phenomenology at low energies. use usual high-scale seesaw suppress all mass term...

The problem of homogenization, i.e. substantial reduction of the electrical size of the average lattice constant, of electromagnetic left-handed (LH), or more generally composite right/left-handed (CRLH) metamaterials (MTMs), is presented. The undesirable effects of an electrical very large structural unit cell are explained and illustrated by full-wave simulations and experiments with CRLH mus...

Unusual narrow transmission bands are found in the Bragg reflective region of a multi-layered structure consisting of alternate right-handed material (RHM) and left-handed material (LHM). These unusual narrow transmission bands may exist no matter whether the optical length of a LHM layer completely cancels that of a RHM layer. However, if they can not cancel each other, it is required that the...
