ORTEGA GONZALEZ, Daryl; GONZALEZ MORALES, Yuri  e  ARZOLA MORRIS, Pedro. Calculation of the dielectric complex permitivity of the absorbent materials withlosses. EAC [online]. 2018, vol.39, n.1, pp. 35-48. ISSN 1815-5928.

Presently work shows up a calculation method of the dielectric complex permittivity of radiofrequency absorbent materials, going by an exhaustive stage of measurement of the dispersion parameters of a line of coaxial built transmission to see the development of the electromagnetic wave in Transverse electromagnetic (TEM) mode. This method whose analysis was carried out in the band of 1-10GHz, it was guided in such way that in it use of the theories of the electromagnetic field is made and that of transmission line and its only requirement is an experimental good base. In the calculations use of the material poliuretanodopado is made with coal activated at the 8%.
