how will you define dielectric matierals?

A dielectric material is one that doesn't conduct electricity and can also be referred to as a conductor. This means they don't have many "free" electrons zooming throughout the material, ie not very many electrons that are tied to one specific atom in your solid. Asbestos and diamond are both examples of conductors.

electricity (î-lèk-trîs´e-tê), class of phenomena arising from the existence of CHARGE. According to modern theory, most ELEMENTARY PARTICLES of matter possess charge, either positive or negative. Two particles of like charge, both positive or both negative, repel each other; two particles of unlike charge are attracted. The electric FORCE between two charged particles is much greater than the gravitational force between the particles. Many of the bulk properties of matter are ultimately due to the electric forces among the particles of which the substance is composed. Materials differ in their ability to allow charge toflow through them. Those that allow charge to pass easily are conductors,  whereas those that allow extremely little charge to pass through are called insulators,  or DIELECTRICS. A third class of materials, called SEMICONDUCTORS, is intermediate. Electrostatics is the study of charges, or charged bodies, at rest. When positive or negative charge builds up in fixed positions on objects, certain phenomena can be observed that are collectively referred to as static electricity. The charge can be built by rubbing certain objects together, such as silk and glass or rubber and fur; the friction between these objects causes ELECTRONS to transfer from one to another with the result that the object losing electrons acquires a positive charge and the object gaining electrons acquires a negative charge. Electrodynamics is the study of charges in motion. A flow of electric charge constitutes an electric current. In order for a current to exist in a conductor, there must be an ELECTROMOTIVE FORCE (emf), or POTENTIAL difference, between the conductor's ends. An electric CELL, a PHOTOVOLTAIC CELL, and a GENERATOR are all sources of emf. An emf source with an external conductor connected from one of the source's two terminals to the other constitutes an ELECTRIC CIRCUIT. Direct current (DC) is a flow of current in one direction at a constant rate. Alternating current (AC) is a current flow that increases in magnitude from zero to a maximum, decreases back to zero, increases to a maximum in the opposite direction, decreases to zero, and then repeats this process periodically. The number of repetitions of the cycle occurring each second is defined as the frequency, which is expressed in HERTZ (Hz). The frequency of ordinary household current in the U.S. is 60 cycles per sec (60 Hz), and electric devices must be designed to operate at this frequency. In a solid, the current consists not of a few electrons moving rapidly but of many electrons moving slowly; although this drift of electrons is slow, the impulse that causes it moves through the circuit, when the circuit is completed, at nearly the speed oflight. The movement of electrons in a current is not steady; each electron moves in a series of stops and starts. In a direct current, the electrons are spread evenly through the conductor; in an alternating current, the electrons tend to congregate along the conductor surface. In liquids, gases, and semiconductors, current carriers may be positively or negatively charged.

Ok, i am an electronics teacher, but it will be very lengthy and cumbersome to explain, because you have to go as deep as electrons and positive and negative charges, so i can advise you to go to www.wikipedia.com and you will find a satisfactory answer.

Debye materials can be thought of as a simple RC circuit where the amount of polarization is re-\nlated to the voltage across the capacitor. The “source” driving the circuit is the electric field. For\na step in source, there may be a constant polarization. As the frequency goes to infinity, the polar-\nization goes to zero (leaving just the constant residual high-frequency term).

Electrical conductivity is a measure of a material's ability to conduct an electric current. When an electrical potential difference is placed across a conductor, its movable charges flow, giving rise to an electric current. The conductivity σ is defined as the ratio of the current density  to the electric field strength :\n\n. \nIt is also possible to have materials in which the conductivity is anisotropic, in which case σ is a 3×3 matrix (or more technically a rank-2 tensor) which is generally symmetric.\n\nConductivity is the reciprocal (inverse) of electrical resistivity and has the SI units of siemens per metre (S·m-1). It is commonly represented by the Greek letter σ, but κ or γ are also occasionally used.

Dielectric constants are a measure of the medium's accomodation to electric fields. Polar solvents have a diploe moment on each molecule. An electric field has to orient them and thus does work. This is the reason for the high values.

Its actually derived from Maxwell's Wave Equations, see source. Its too complex and requires mathematic symbols, so I can't type it here.

The following refers to Coulomb force between two charges in a single uniform medium, not the two-medium situation described in  the question.\nAnswer 1 is helpful but the lack of exponent signs makes it misleading. The force is inversely proportional to the square of the distance, so the simplified formula is \nF = k * q1 * q2 / r^2 \nk is a constant = 8.99*10^9 N m^2 / C^2 (C is charge in Coulombs). Thus if q1 = q2 = 1 Coulomb, and q1 is separated from q2 by r = 1 meter, the force is 8.99*10^9 N or 2.01 billion pounds! \nThe above simplified formula is a contraction of the full formula (see ref.),\nF = q1 * q2 / (4 * pi * epsilon * r^2)\nin which k is replaced by 1/(4 * pi * epsilon), where epsilon is the product of epsilon0, the electrical permittivity of the vacuum (= 8.85 * 10^-12 c^2/(N m^2)), and kappa, the dielectric constant which = 1 for vacuum and is assumed in the simplified formula.\nFor two segments of distance as you specify, first solve for F1 and F2, each as a function of a particular distance (r or d - r) and dielectric constant. Then my inclination would be to try the sum-of-inverse square root solution which works for a similar situation, gravitational force F at distance R, computed from F1 and F2 at partial distances R1 and R2, where R = R1 + R2, \n1/SQRT(F) = 1/SQRT(F1) + 1/SQRT(F2)\nSorry I can't be more definite than that.

Mica dielectric has a very low loss and has a fairly stable capacitance at even VHF.
