Dielectrics is a fancy term for insulators, based on the material used and its efficiancy at a measured range of frequencies. For example, in a coaxial cable, the better it isolates the main frequency from feeding through to the shield, the higher the dielectric value.

Electromagnetic waves in lossless dielectric and lossy?
plane waves in lossy dielectrics
Define mica capacitor?
A mica capacitor is simply one that uses the mineral mica as the dielectric or insulator between plates.
What are the evidences of a corona discharge?
When Corona Discharge occurs it forms ozone and nitrogen oxides. These combined with moisture to prduce nitric acid, which is destructive to most dielectrics and certain metallic compositions, resulting in corrosion. In addition, the high energy in some discharges results in mechanical, electrical, and thermal damage. SC
What are the types of polarization?
electronic polarization ionic or atomic polarization orientation or dipole polarization space charge polarization
What is the material use in the capacitor?
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.
