Often the ocean acoustic environment is not well known and sonar performance prediction will be affected by this uncertainty. Here, a method for estimating transmission loss TL is proposed which incorporates these environmental uncertainties. Specifically, we derive an approach for the statistical estimation of TL based on the posterior probability density of environmental parameters obtained f...

In this paper we proposed the method for calculation of resonant frequencies of split-ring resonators (SRRs) as a function of the angle between slits. Method is based on transmission line (TL) approach and can be used for calculation of resonant frequencies of broadside and edge-coupled, as well as of multiple SRRs. Resonant frequencies are also calculated using 3D EM simulations based on metho...

In this paper a metamaterial-inspired antenna with high gain and good directivity is designed. Based on the concept of composite right/left-handed transmission line (CRLH-TL), the proposed antenna is realized based on three leakage wave unit cell and a left handed circular ring slot incorporated on the surface. The maximum achievable gain at the resonant frequency of 5.6 GHz is 6.933 dBi, and t...

Accurate parameters of transmission line (ParTL) are the basis power system analysis. For high-voltage (TL), remote terminal units (RTUs) widely installed to provide supervisory control and data acquisition (SCADA) measurements. Based on multiple snapshots SCADA at both ends TL, a four-step method identify ParTL is proposed in this paper. In detail, based π-model relationship between voltage ph...

In this paper, we consider a two-level system (TLS) coupled to a one-dimensional continuum of bosonic modes in a transmission line (TL). Using the master equation approach, a method for determining the photon number distribution of the scattered field is outlined. Specifically, results for the reflected field when driving the TLS with a coherent pulse are given. While the one-photon probability...

Metamaterials have emerged as promising solutions for manipulation of sound waves in a variety of applications. Locally resonant acoustic materials (LRAM) decrease sound transmission by 500% over acoustic mass law predictions at peak transmission loss (TL) frequencies with minimal added mass, making them appealing for weight-critical applications such as aerospace structures. In this study, pot...

A novel backward microstrip coupled-line coupler which has been designed based on the metamaterial and composite right/left handed (CRLH) transmission line (TL) concepts is proposed. Coupling coefficient, bandwidth and size of proposed microstrip coupler are improved by coupled interdigital TLs which have been realized only by one interdigital capacitor. The design procedure to reach the couple...

The present study aimed to develop novel solid dispersion (SD) of tranilast (TL) using amphiphilic block copolymer, poly[MPC-co-BMA] (pMB), to improve the dissolution and pharmacokinetic behavior of TL. pMB-based SD of TL (pMB-SD/TL) with drug loading of 50% (w/w) was prepared by wet-mill technology, and the physicochemical properties were characterized in terms of morphology, crystallinity, di...

Abstract The paper demonstrates an effective technique to significantly enhance the bandwidth and radiation gain of otherwise narrowband composite right/left-handed transmission-line (CRLH-TL) antenna using a non-Foster impedance matching circuit (NF-IMC) without affecting antenna’s stability. This is achieved by negative reactance NF-IMC counteract input capacitance antenna. Series CRLH-TL uni...
