An ultra-broadband single-component fractional-order capacitor using MoS2-ferroelectric polymer composite

Dielectric Properties and Morphology of Ferroelectric Ceramic-Polymer Composite Films

Dielectric constant and morphology of BaTiO3-polymer composite films were studied as a function of the filler concentration. The morphology of the films was examined using laser scanning confocal microscopy, which is capable to measure small particle distributions in more details than conventional microscopy. The thin-slice images allowed us to visualize the micronsize particles and the polymer...

Design of an Ultra-Wideband Monopole Antenna by Using New Nano-Composite Materials

In this paper, a planar monopole antenna is introduced, also we added some new Nano fillers such as Fumed Silica and Aluminum Oxide to RT Duriod5880 and RO3003 to produce new Nano composite materials, then new Nano composite materials are used as a substrate of a ultra-wideband monopole antenna. Antenna characteristics are considered to illustrate that, by using these Nano composite materials, ...

Design of ultra-broadband terahertz polymer waveguide emitters for telecom wavelengths using coupled mode theory.

We use coupled mode theory, adequately incorporating optical losses, to model ultra-broadband terahertz (THz) waveguide emitters (0.1-20 THz) based on difference frequency generation of femtosecond infrared (IR) optical pulses. We apply the model to a generic, symmetric, five-layer, metal/cladding/core waveguide structure using transfer matrix theory. We provide a design strategy for an efficie...

Ultra-thin Graphene/Polymer Layered Composite Membranes for NEMS applications

Single layer chemical vapor deposited (CVD) graphene has shown great promise in enabling Micro and Nanoelectromechanical Systems (MEMS/NEMS) that can outperform current silicon-based state of the art. However, current methods in forming single layer graphene MEMS devices result in low yields due to capillary effects acting on the suspended material during the graphene transfer process. In addit...
