Superconductivity is the set of physical properties observed in certain materials, wherein electrical resistance vanishes and from which magnetic flux fields are expelled. Any material exhibiting these properties is a an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered even down to near absolute zero, a superconductor has a.

Abstract: Microwave-absorbing materials find application in telecommunications, microwave heating and for representing the behavior of biological tissue in the presence of microwave radiation. Commonly, such materials are formed using ferromagnetic filler particles and rely on the phenomenon of ferromagnetic resonance for absorption of by: A ferromagnetic core, called E-, I-, U-, L-, toroidal, pot, or planar cores, depending on their shape Primary and secondary coils, also known as windings When the device is connected to two (or more) circuits, it transfers the electrical current via electromagnetic induction.

This paper discusses a new type of wire media based on amorphous ferromagnetic microwires. The combination of two effects, namely, a strong dispersion of the effective permittivity in . Ferromagnetism is a kind of magnetism that is associated with iron, cobalt, nickel, and some alloys or compounds containing one or more of these elements. It also occurs in gadolinium and a few other rare-earth elements. In contrast to other substances, ferromagnetic materials are magnetized easily, and in strong magnetic fields the magnetization approaches a definite limit called saturation.

Plasma, in physics, an electrically conducting medium in which there are roughly equal numbers of positively and negatively charged particles, produced when the atoms in a gas become ionized. It is sometimes referred to as the fourth state of matter, distinct from the solid, liquid, and gaseous states. We report tunable band gaps and transport properties of B-doped graphenes that were achieved via controllable doping through reaction with the ion atmosphere of trimethylboron decomposed by microwave plasma. Both electron energy loss spectroscopy and X-ray photoemission spectroscopy analyses of the graphene reacted with ion atmosphere showed that B atoms are substitutionally Cited by: Co-based amorphous microwires presenting the giant magnetoimpedance effect are proposed as sensing elements for high sensitivity biosensors. In this work we report an experimental method for contactless detection of stress, temperature, and liquid concentration with application in medical sensors using the giant magnetoimpedance effect on microwires in the GHz range.

In the microwave plasmas, the microwave power is transferred via a waveguide (or via a coaxial cable) and is launched to the plasma generation region through a dielectric window, which is configured at one face of the waveguide (or through a dielectric tube surrounding the inner electrode of the coaxial cable).

We report the observation of multiple permeability peaks for thin ferromagnetic films, in the 10 MHz to 6 GHz range. This behavior is correlated with the presence of perpendicular anisotropy and stripe domains. Because the perpendicular anisotropy is much smaller than the saturation magnetization of the layer, we propose an adaptation of the classical domain mode resonance model to the Cited by: The 4th edition of this classic text provides a thorough coverage of RF and microwave engineering concepts, starting from fundamental principles of electrical engineering, with applications to microwave circuits and devices of practical importance.
