In dielectric spectroscopy, an analysis is made of the function of the

complex permeability [[epsilon].

The reflection loss (RL) of composite nanofibers was calculated by Matlab based on the relatively complex permeability and permittivity at a given frequency and matching thickness according to the following equations:

r] = [mu]' - j [mu]") is the relative complex permeability, j represents the imaginary part, dB represents the unit of attenuation values of incident radar wave, f is the frequency of the EM wave, d is the coating thickness, c is the velocity of light, [Z.

Complex permeability ([mu]' and [mu]") was calculated from [B.

Lossy magnetic wires are characterized by a

complex permeability [[mu].

Conventional spinel type ferrites do not function well in the GHz range due to a drop in the

complex permeability ([[mu].

Application of materials in the microwave, aerospace, and communications demands an accurate knowledge of material properties such as complex permittivity and

complex permeability.

The properties of a material may be specified by two complex constants called complex permittivity ([epsilon]) or dielectric constant and

complex permeability ([mu]).

The shorted microstrip transmission-line perturbation (SMTLP) measurement technique was used to determine the

complex permeability of the cobalt nanoparticle thick films [28, 30-33].
