A new structure of microstrip-based low-pass filter with wide stopband and sharp roll-off is introduced, in this paper. In the proposed topology, resonators T modified L Shapes have been used. To improve suppression factor relative bandwidth, second resonator has added to first resonator. The designed fabricated on a 20 mm thickness RO4003 substrate, which loss tangent 0.0021 dielectric constan...

Abstract The primordial spectrum of fluctuations may present a large peak as result enhancing features during inflation. This include, but is not limited to, bumps in the inflaton's potential, phases ultra-slow-roll or turns multi-field space. However, many models, inflation does end immediately after feature and it likely to continue with second phase slow-roll. We show that resulting induced ...

We present results of a simulation study of inelastic hard disks vibrated in a vertical container. An event-driven molecular dynamics method is developed for studying the onset of convection. Varying the relevant parameters (inelasticity, number of layers at rest, intensity of the gravity) we are able to obtain a qualitative agreement of our results with recent hydrodynamical predictions. Incre...

We develop an integral form for the bispectrum in general single-field inflation whose domain of validity includes models of inflation where the background evolution is not constrained to be slowly varying everywhere. Our integral form preserves the squeezed-limit consistency relation, allows for fast evaluation of the bispectrum for all triangle configurations expediting the efficient comparis...

We report on the manufacture of a first batch of approximately 2,000 Gas Electron Multipliers (GEMs) using 3M’s fully automated roll to roll flexible circuit production line. This process allows low-cost, reproducible fabrication of a high volume of GEMs of dimensions up to 30×30 cm. First tests indicate that the resulting GEMs have optimal properties as radiation detectors. Production techniqu...

Using the Effective Field Theory (EFT) framework of single field inflation, we investigate possibility formation Primordial Black Holes (PBHs) in Slow Roll (SR) to Ultra (USR) sharp transition. We demonstrate that, due one-loop correction power spectrum, causality is violated (cs>1) for mass range PBHs, MPBH>102gm created during said find that non-canonical features with cs<1 worsen predictions...

in this paper, the effects of roll center height of mcpherson suspension mechanism on dynamic behaviour of a vehicle is studied first and then the optimum location of roll center of this suspension system is determined for a conceptual class a vehicle. adams/car software was used for analysis of vehicle dynamic behaviour in different positions of suspension roll center, then optimization proces...

This paper reports an Ultra wideband pass filter with a center frequency of 3.96 GHz and 3 dB bandwidth of 1584 MHz. The filter design is based on transversal signal interference principle implemented by means of transmission lines.The features of this filter include low insertion loss, sharp rejection along with simple design approach. Also, comparison of simulation and measured filter paramet...

A compact ultra-wideband (UWB) power divider with favorable selectivity is proposed. A transversal filtering transformer consisting of two different centrally loaded resonators with common feeding lines is introduced at input port to obtain good in-band response and high out-of-band rejection. Simple and rapid design procedure is adopted to find the key parameters. A prototype power divider is ...
