Probehead with interchangeable tunable bridged loop
... In this design the capacitance of the resonator is not defined by the volume between the two open ends of the loop but by the volume between the loop ends and the bridges ~Fig. 1!. This leads to a more homogeneous microwave magnetic field distribution over the sample volume and confines the electric ...

Stress relaxation in aging soft colloidal glasses
... [the integral can be considered as a summation over various si]. This suggests a possible scenario, wherein an applied step strain can overpopulate the long time tail, while rejuvenating the short time tail of the distribution of relaxation times. This would lead to a decrease in the modulus but an ...

Dielectric
A dielectric material (dielectric for short) is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction. This creates an internal electric field that reduces the overall field within the dielectric itself. If a dielectric is composed of weakly bonded molecules, those molecules not only become polarized, but also reorient so that their symmetry axes align to the field.The study of dielectric properties concerns storage and dissipation of electric and magnetic energy in materials. Dielectrics are important for explaining various phenomena in electronics, optics, and solid-state physics.
