Abstract We present recent 2-port vector network analyzer (VNA) measurements of the complete set scattering parameters for antenna used within Long Wavelength Array (LWA) and associated front end electronics (FEEs). Full parameter yield not only reflection coefficient each polarization, S11 S22, but also coupling between polarizations, S12 S21. These had been previously modeled using simulation...

A true-time delay (TTD) cell in TSMC 0.18 μm CMOS technology for 1–5 GHz applications is presented. Process variations, ageing effects, field and other non-idealities have some impacts on the TTD cell's devices. One of vulnerable specifications cells their variation. While works a line, must constant robust frequency band. For this matter, body bias technique presented applied to inductor-less ...

We present a computationally efficient implementation of double-hybrid density functional theory (DH-DFT) leveraging the dual basis methods Head-Gordon and co-workers resolution-of-the-identity second-order Møller-Plesset (RI-MP2) theory. The B2PLYP, B2GP-PLYP, DSD-BLYP DSD-PBEP86 functionals are applied to assess performance dual-basis on several benchmark test cases, including CONF set confor...

Abstract The thermal properties of polymeric nanocomposites can be examined using TGA and DSC techniques, while dielectric through simulated scattering (S11, S12, S21, S22) parameters. Polyaniline (PAni) nanopowder was synthesized chemical oxidative polymerization techniques. Consequently, the crystallite size morphology powder were XRD, TEM, FESEM Further, a series developed via wet mixing com...

The depolymerization of enzymatic hydrolysis lignin (EHL) is examined over one-step hydrothermal-synthesized MoS2 in ethanol without hydrogen gas. Value-added aromatic molecules, mainly including alkyl-substituted phenols (A-Ps), are obtained char or tar formation. samples prepared with different Mo and S precursors have been tested the highest monomer yield 226.4 mg/g EHL achieved thioacetamid...
