Characterization of Dielectric Anisotropy of Reinforced Substrates at Different Temperatures

Autor: Plamen I. Dankov, Valda P. Levcheva, Mario Iliev

Publikováno v: 2020 XI National Conference with International Participation (ELECTRONICA).

The authors' two-resonator method has been modified for temperature characterization of the reinforced substrates used in the microwave electronics and especially their uni-axial anisotropy (different dielectric constants in parallel and perpendicula

Practical Isotropy and Anisotropy of 3-D Printed Artificial Foam-Like Dielectrics with Antenna Applications

Autor: Mario Iliev, Valda P. Levcheva, Plamen I. Dankov

Publikováno v: 2018 12th International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials).

The models, limitations and realization of homogenized foam-like 3-D printed dielectrics have been presented applying different fully symmetrical unit cells. The strategy for control of the absolute values of the resultant isotropic equivalent dielec

Effect of Sample Configuration on the Morphology of Foamed LDPE/PP Blends Injection Molded by a Gas Counterpressure Process

Autor: Georgi Kotzev, María L. Cerrada, Manya Krasteva, Ernesto Pérez, Strashimir Djoumaliisky, Mario Iliev

Publikováno v: Macromolecular Materials and Engineering. 292:769-779

Blends of isotactic poly(propylene) and low-density polyethylene with different composition ratios were prepared through direct melt compounding on a twin-screw extruder. The specimens with various geometric configurations were injection-molded using
