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.

A mica capacitor is simply one that uses the mineral mica as the dielectric or insulator between plates.
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

In waveguides, dielectric materials are used to separate conductive elements and influence the propagation of electromagnetic waves. Common dielectric materials include air, plastics, ceramics, and glass, depending on the frequency range and application. These dielectrics help maintain the waveguide's operational efficiency by reducing signal loss and controlling the wave's mode structure. The choice of dielectric affects the waveguide's characteristics, such as its cutoff frequency and bandwidth.
The micas are used as dielectrics.

The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
