In this paper, we examine changes of the electric field distributions in waveguide-based axial-type microwave plasma source (MPS) during tuning procedure. The distributions strongly depend on position of the movable short, so does the wave reflection coefficient of the incident wave. A ... Per saperne di più
Finite element modeling of three-phase induction machines requires the solution of coupled circuit and field equations. This work aims to solve this problem using a strong coupling approach. This work includes circuit field coupling and proper air-gap meshing, using the AC/DC Module of ... Per saperne di più
Power grid voltages and currents may be distorted due to presence of harmonics. Measurements of such voltage with harmonics may be performed using newly developed instrument with a small air-core transformer based probe as the input unit. The probe must be shielded against unknown ... Per saperne di più
In this work, we show that dipolar magnetic coupling can be used to control the particle flow through microfluidic structures without changing the state of motion of the carrier liquid. Also no external magnetic gradient fields are employed; the total external magnetic force applied is ... Per saperne di più
Domestic microwave ovens are notorious for their uneven heating of food materials. This is caused by a varying electromagnetic field whose variation is caused by a number of factors dependent on the oven and the food parameters. Experimental validation of heating would therefore give ... Per saperne di più
Interaction between the probe and a defect in eddy current non-destructive evaluation is studied. Evaluation of sensor signal response is the basis for the calculation. In this work a differential sensor is considered and the problem regarded here is problem 8 from the testing of ... Per saperne di più
ICP reactors are usually meter sized and driven at RF frequencies, for example at 13.56 MHz. We developed a miniature resonator allowing an inductive type of coupling of microwaves at 2.45 GHz to a plasma jet, flowing in ceramic tubes. Previous experiments and simulations show an ...

Coil antenna is the simplest form in well-logging tools for resistivity measurement of the formation. This paper introduces how to accurately compute the impedance of the coil with very thin wires at high frequency, and with the complex borehole structure, e.g., metal housing and ...

‘Metamaterial’ is one of the most recent topic in several areas of science and technology due to its vast potential in various applications. These are artificially fabricated materials which exhibit negative permittivity and/or negative permeability. The unusual electromagnetic ... Per saperne di più
A common clinical treatment is the application of alternating electromagnetic fields using a screw implant to the weak bone tissue within the femoral head, which speed up the bone regeneration in case of avascular necrosis of the femoral head . In our present work the bipolar induction ... Per saperne di più
