The term "artificial dielectric" is conveniently applied to any arrangement of conducting obstacles which affects the propagation of electromagnetic waves in a way similar to a solid dielectric. The essential property of a solid dielectric from the point of view of propagation is that the phase velocity within the dielectric is different from the free-space value. A quantitative indication of t...

The high-k dielectric TiO2/ZrO2 bilayer composite film was prepared on a Si substrate by radio frequency magnetron sputtering and post annealing in N2 at various temperatures in the range of 573 K to 973 K. Transmission electron microscopy observation revealed that the bilayer film fully mixed together and had good interfacial property at 773 K. Metal-oxide-semiconductor capacitors with high-k ...

The electric polarizability of DNA, represented by the dielectric constant, is a key intrinsic property that modulates DNA interaction with effector proteins. Surprisingly, it has so far remained unknown owing to the lack of experimental tools able to access it. Here, we experimentally resolved it by detecting the ultraweak polarization forces of DNA inside single T7 bacteriophages particles us...

The complex dielectric constants at room temperature of various goat tissues (liver, muscle, kidney, heart and brain) and corn syrup were measured in the frequency range 1 to 10 GHz with the help of a HP Network Analyzer N5230A. Open ended coaxial cable method was employed for the measurement. The system imperfections are completely avoided by calibrating the system with four known materials an...

This paper reports on an investigation into the effects of different multi-element oxide nanofillers structure and dielectric properties polypropylene (PP)-based nanocomposites. Magnesium aluminate (MgAl2O4), calcium carbonate (CaCO3) surface-modified (CaCO3T) have been added to PP determine their thermal properties, structural changes, response breakdown strength. The results show that nanocom...
