Electromagnetic waves are a radio, light, X-rays and gamma rays. However, traditionally electromagnetic waves considered in scientific and in academic literature in different positions. Radio waves are always considered as a waves, while light is represen... see more

An in-depth analysis of the dynamics connected to the Doppler-effect brings clear light to elements of contradiction with the original ground on which the axiom of the constancy of lightspeed was based.Thereby, with regard to electromagnetic phenomenology... see more

The anechoic chamber is closely related as a device for precisely measuring various acoustic characteristics. Anechoic chambers room conditions controlled to produce a sound field-free space. This study focused on testing various commercial wedges such as... see more

The paper presents the results of the study of properties of fast surface electromagnetic waves that propagate along the flat interface between the active metamaterial and air (or vacuum). The case of homogeneous and isotropic metamaterial is conside... see more

Stealth technology in terms of absorption of electromagnetic waves is a most valuable research area for military purposes. Development of radar absorbing materials (RAM) had been actively researched for a quite long time. In the RAM design, weight, thickn... see more

The slow surface electromagnetic waves that propagate along the planar waveguide structure that contains two identical isotropic left-handed material with the vacuum (or air) gap has been considered. The possibility of propagation of slow surface&nbs... see more

This paper presents the construction, mathematical modeling and testing of a scaled universal hydraulic Power Take-Off (PTO) device for Wave Energy Converters (WECs). A specific prototype and test bench were designed and built to carry out the tests. The ... see more

Geoelectrical and geomagnetic fluctuations are considered the end product of several geophysical phenomena. Inparticular these signals measured in seismically active areas can be attributed to stress and strain changes associatedwith earthquakes. The comp... see more
