Opis:: The main objective of the paper is to overview of the actual and potential capabilities of some complex multilayers to enhance, and control the microwave absorption. Going through available literature data we emphasize the role of interphase coupling, and material resonances in enhancing phenomena of importance for internal scattering, diffusions, and intrinsic material absorption of propagating EM wave, especially in microwave and mm wave ranges. The theoretical background is consequently formulated in terms of transmissions line approach.

Opis:: Pb-based complex perovskites with $Fe^{3+}$ like $Pb(Fe_{2//3}W_{1//3})O_3$ were found to be interesting because of their unique properties such as relaxor and magnetoelectric behavior. $Pb(Fe_{2//3}W_{1//3})O_3$ is ferroelectric with ferroelectric Curie temperature $T_{C}$ between 150 and 200 K and at the same time is antiferromagnetic with magnetic Néel temperature about 400 K. $BiFeO_3$ is a well known perovskite compound which exhibits ferroelectric ($T_{C}$ = 1103 K) and antiferromagnetic ($T_{N}$ = 643 K) ordering simultaneously. The polycrystalline sample of $0.3Bi_{0.95}Dy_{0.05}FeO_3-0.7Pb(Fe_{2//3}W_{1//3})O_3$ were synthesized using standard sintering procedure. Magnetization vs. magnetic field (at 4.2 K) curves were measured. Magnetoelectric properties of the sample were obtained.

Opis:: Measurements of magnetization and electric polarization performed for the $TbMnO_3$ film grown onto the single crystal [100] $SrTiO_3$ substrate using magnetron sputtering technique exhibit series of anomalies related to the magnetic and electric ordering of the $Tb^{3+}$ and $Mn^{3+}$ sublattices. The detailed temperature dependences of the electric polarization and dielectric constant of the $TbMnO_3$ film have shown that the ferroelectric phase appears below 30 K in magnetic field H > 1 T applied in-plane and out-of-plane of the film.
