dielectric

 [di″ә-lek´trik]
1. transmitting electric effects by induction, but not by conduction. The term is applied to an insulating substance through or across which electric force is acting or may act, by induction without conduction.
2. an insulating substance that transmits in this way, i.e., through or across which electric force is acting or may act, by induction without conduction.

At high frequencies (>900 KHz), the capacitors with dielectric materials [M.sub.1][A.sub.3][PA.sub.6]-BT and [M.sub.7][A.sub.2]PA1- BT tend to take a constant value of capacitance.
In addition to investigation on Material A, some preliminary studies were also carried out by applying the new SAP technique on other rigid dielectric materials (Material B, Material C, Material D and Material E).
When the frequency given to dielectric material is increased beyond a specific limit the electron exchange between Fe2+ and Fe3+ ions does not follow the variations of applied field, and the value of dielectric constant almost becomes constant.
If a dielectric material with a higher dielectric constant (high-[kappa]) can replace Si[O.sub.2], the dielectric layer thickness can be increased proportionally while keeping the same gate capacitance [2, 3].
Five groups of p-substrate MOS devices have been analyzed consisting of two high-k dielectric materials, Zr[O.sub.2] and Hf[O.sub.2], having the dielectric constant of 22 for amorphous structure of the materials [13].
These two measures of parameter [gamma]l [3, 4] allow easy access, theoretically, to parameters [[epsilon].sub.r] and tan [[delta].sub.d] of the dielectric material.
The other way to construct this variant is to build the circuit as a normal flex, then laser-ablate the dielectric material from the window areas on both sides of the circuit, thereby leaving unsupported conductors.
However, in the case of dielectric materials, a certain amount of energy, proportional to the transmission coefficient between the air and the dielectric, will propagate through the material [1].
Figures 6 and 7 show the even- and odd-mode impedance of PCPW embedded in two dielectric materials of different heights and on top of two-layered substrate, respectively, with parameters listed in the figures.
Further, effect of multiple probes on DRA [21] and loading monopole with dielectric material [22] for wideband applications have also been studied.
The method of the paper [7] was used to determine the relative complex permittivity of seven low-loss dielectric materials cited above.
The Presense LDS300 is a level detection and switching system for solids and liquid in tanks, hoppers, vessels or containers that is particularly suitable for measuring in harsh, pressurised, abrasive, hot and corrosive environments and with low dielectric materials.
