Abstract

The paper investigates absorption of electromagnetic waves by radio engineering structures, filled with liquid dielectrics, in which characteristic size of heterogeneities is much less compared to the wavelength. These structures can be treated as composite materials, possessing effective dielectric constant. Their electrodynamic properties can be computed using equations, derived for composites. An approximate computation method is offered, allowing to compute electrodynamic properties of the structure in analytical form, using equations for the effective dielectric constant of laminated composites. Computed dependencies of electrodynamic properties as a function of structure geometry and dielectric properties of liquids are presented in explicit form, making it easier for analysis, compared to numerical results, obtained by rigorous electrodynamic methods. For a wide range of structures effective dielectric constants and reflection coefficients for the case `absorbing structure on metal' have been computed. A good agreement of computed and experimental results has been observed.
