Generally speaking, the permeability of a magnetic material is greater than 1, and the dielectric coefficient of a dielectric material is greater than 1. Traditional magnetic materials emphasize that their permeability is greater than 1, without characterization or dielectric coefficient.
In electromagnetics, permeability is the degree to which a material responds linearly to an applied magnetic field. Permeability is usually expressed by the Greek letter mu. This form was created and used by Oliver Heviside in September 1885. Relative permeability is commonly used to characterize material parameters in magnetic material engineering. Dielectric coefficient, or capacitance, is an indicator of the ability of a material to store charges. The magnetic antenna described in this paper refers to the antenna loaded with magnetic material (permeability greater than or equal to 1) and dielectric material (dielectric coefficient greater than or equal to 1). Because in the calculation of antenna index, the product of the two parameters is called antenna shrinkage factor. The relationship between the multiplication of the two shows that they can be exchanged.
