The paper is devoted to experimental investigation of the spatial distribution of electromagnetic field in the vicinity of the tapered wire medium formed by copper wires conductors in the millimeter waveband. The technique of small perturbations was applied to analyze the spatial distribution of the field intensity in cross-section of the wire medium. The optimal type of probe has been found. The...
The work purpose is the study of a spatial electromagnetic field distribution in metamaterials (periodical structures - photonic crystals (PC), complex media), and the development of the corresponding technique both for GHz and THz frequency band. The technique of the recording of spatial field distribution in one-dimensional photonic crystal in microwave band using the method of a passive and active...
We report the results of direct mechanical tests of the fibrous periosteum from the tibiotarsi of white leghorn chicks at 4, 6, 8, 9, 10, 11, 12, and 14 weeks of age using a newly developed sample isolation technique. Additionally, this technique allows the determination of the apparent in vivo load on the fibrous periosteum. The periosteum has a highly nonlinear stress-strain relationship at all...
