The physical basis for determining the complex wavenumber for electromagnetic waves propagating through a layer of carbon fiber
Incoming article date: 28.03.2022The conclusion of the relations for the study of the propagation or diffraction of electromagnetic waves in the semiconductor layers of composite materials, which are also recommended to be used in the creation of onboard antennas and microwave devices with less weight. Both exact and simplified mathematical expressions for the rapid quantitative estimation of the complex wave number are obtained. Using the example of carbon fiber plastics with high conductivity, it is shown that their use makes it possible to create waveguide paths and antenna reflectors up to a millimeter wavelength range.
