Individual electrons in graphene behave as massless quasiparticles. Unexpectedly, it is inferred from plasmonic investigations that electrons in graphene must exhibit a non-zero mass when collectively excited. The inertial acceleration of the electron collective mass is essential to explain the behaviour of plasmons in this material, and may be directly measured by accelerating it with a time-v...

In terms of high-current measurement capacitors, PCB Rogowski coils have attracted much attention because their small size and easy installation. However, they are vulnerable to electromagnetic interference. order improve the immunity coil, this paper studies influence structure parameter changes double-layer coil on accuracy mutual inductance. By testing frequency response four common structur...

Abstract. A correction model for eddy correlation flux measurements is developed and applied to nitrogen dioxide flux measurements obtained from a SOLENT sonic anemometer and a Scintrex Luminox LMA-3 analyser for NO2. Four field campaigns were carried out near the village of Merenschwand in Central Switzerland from which two were selected for further analysis in this paper. The need for the cor...

Inductance measurements is important for all branches of technology related to the application electricity: energy and electronics, radio television, transport communication, scientific research. Electromechanical devices electronic components can be characterized using impedance identify parameters their equivalent electrical model. New inductance measurement methods are being developed in spe...

Abstract: Design, simulation, and implementation of microstrip spiral inductors for RF applications at the high frequency (HF) range are given. The simplified lumped element equivalent model parameters for spiral inductor are used to obtain the initial physical dimensions for the design. The spiral inductor is then simulated with planar electromagnetic simulator, Sonnet, using the geometry cons...

In this paper we propose a practical approach for on-chip inductance extraction. This approach differs from previous methods in that it uses circuit characteristics to obtain a sparse, stable and symmetric inductance matrix, using the concept of resistance dominant and inductance dominant lines. Experimental results show that only the important inductance terms related to strong inductance coup...
