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.

Parametric studies based on varying the filter's geometrical parameters as well as the host dielectric medium were thoroughly conducted and several remarks based on the suppression band of the proposed filter were highlighted in the context of the discussed results.
M(x', y', z') is an arbitrary point inside the dielectric medium and [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] are the distances of separation between M and, respectively, [O.sub.m] and [M.sub.i] at time t.
Our results are based on the discussion presented in 14], where the calculation of the electromagnetic field distribution on an axisymmetric resonator is generalized to an arbitrary number of dielectric media embedded in an outer dielectric resonator, and they will be particularized in this work to study the simpler case of a resonator made by only one dielectric medium.
The fusion bonding of multilayer structures provides a homogeneous dielectric medium that can integrate both active and passive functional elements for superior electrical performance at microwave frequencies.
Deionized water is the principal dielectric medium used on wire EDM machines.
Water is a dielectric medium. All forms of precipitation, independent of density, have dielectric constants much greater than air.
The system we study consists of a dielectric medium whose dielectric constant is [[epsilon].sub.1] in the region [x.sub.3] >[zeta]([x.sub.1]) and a dielectric medium whose dielectric constant is [[epsilon].sub.2] in the region [x.sub.3] <[zeta]([x.sub.1]) (Figure 1).
The authors report a novel process for the production of PCBs and IC packaging using glass as both a dielectric medium and a platform for wiring simultaneously.
The EDM machine is cleaned and the dielectric medium is mixed in a definite proportion and it is kept in a separate tank which having capacity of 4 litres.
Next we will study the case when the object to be hidden is not a PEC but some dielectric medium (same size as the object to be hidden in Fig.
For low frequency dielectric studies the pellet was made in the form of a disc capacitor with the specimen as the dielectric medium. Both the flat surfaces of the sintered pellet were polished and then electroded by applying silver paste.
