GB/T 4365 and GB/T 9637-2001 define the following terms and definitions apply to this document.
3.1 Gyromagneticeffect
After the magnetization of the material or medium under the action of the static magnetic field is perturbed, the basic magnetic dipole passes around the direction of the strength of the static magnetic field
The effect of damping precession, relaxation back to equilibrium.
[GB/T 9637-2001, Definition 2.5, 221-05-01]
3.2 Non-gyromagnetic solid material
Solid materials that do not have a gyromagnetic effect.
3.3 Complex relative permittivity
Complex relative permittivity is expressed as.
epsilonr = epsilon'r-jepsilonr "=
epsilon0E (1)
In the formula.
epsilonr --- complex relative permittivity;
epsilon'r --- real relative dielectric constant, the real part of complex relative permittivity;
