“…Magnetoelectric coupling shows great promise for achieving tunable devices 15 16 17 18 19 where the impedance in a specific frequency range can be changed according to the input signal. Recently, such devices need to operate in a wide frequency band that includes both digital and analogue broadcasts.…”

The electric and magnetic properties of matter are of great interest for materials science and their use in electronic applications. Large dielectric and magnetoelectric responses of materials at room temperature are a great advantage for electromagnetic device applications. Here we present a study of FeCo-MgF nanogranular films exhibiting giant dielectric and magnetoelectric responses at room temperature; with dielectric constant ε′=490 and magnetoelectric response Δε′/ε′0=3%. In these films, Fe-Co alloy-based nanometer-sized magnetic granules are dispersed in a Mg-fluoride-based insulator matrix. Insulating nanogranular films are a new class of multifunctional materials. The giant responses are caused by spin-dependent charge oscillation between magnetic granules via quantum-mechanical tunnelling. A possible application of such insulating nanogranular materials with giant response is in the construction of a tunable device, in which impedance components such as capacitance and inductance are tunable at room temperature.

“…The impedance matching between an RF generator and a plasma chamber is an integral factor in RF systems to maximize RF power absorbed in plasma, lessen inadequate damage to equipment such as a RF generator and matching components, and maintain processing reproducibility and stability. Various impedance matching networks and algorithms for a wide-range and high-speed matching performance have been developed for lots of plasma sources such as real-time matching for pulsed and continuous wave plasma sources [6][7][8][9][10][11]. Especially, a wide range of impedance matching techniques have received a lot of attention because of industrial needs in order to cover various optimum plasma processing windows (condition) by using a few matching equipment.…”

Despite the fact that a radio frequency (RF) shielding box affects a coil inductance used in matching network, RF engineers have used a coil inductance measured in open space on designing matching networks since it is difficult to precisely measure the coil inductance within the RF shielding box. In this work, we investigate the influences of the RF shielding box on the coil inductance via a 3D full electromagnetic wave simulation. Simulation results shows that the coil inductance decreases from −6.0% to −11.9% compared with its ideal inductance depending on coil positions within the RF shielding box. Both inductive and capacitive coupling between the coil and surfaces of the RF shielding box contribute to the reduction of the coil inductance. We expect that these results would be useful for those who design RF matching networks.
