The Saab Group, Linköping, SwedenFlexibility was required by the Saab Group who wanted to simulate the striking of airplane wings by lightning, as well as how much the shielding material...
Benet Laboratories, US Army Research Engineering and Development Command, Watervliet, NYRailguns-which propel a projectile using electromagnetic forces´ promise to revolutionize projectile launchers. To adequately design them, researchers must...
Riboug Research Centre, Schlumberger, FranceDrilling an oil well requires a good knowledge of the subsoil. Electrical imaging provides a fuzzy picture of underground structures, which needs to be...
MEDRAD's Innovations Group, Indianola, PAMuch of MEDRAD´s research deals with the most efficient yet safest way to deliver diagnostic fluids into a patient´s body. And while fluid dynamics plays a...
SRON (Netherlands Institute for Space Research), Utrecht, NetherlandsXEUS (The X-Ray Evolving Universe Spectrometer) is a mission being conducted by the European Space Agency with the goal of gaining a better view of the...
ASM Assembly Automation Ltd of Hong KongPorous air bearings are a critical element of high-precision machinery thanks to their essentially frictionless operation, high speed, and accuracy. Thanks to...
A Helmholtz coil is a parallel pair of identical circular coils spaced one radius apart and wound so that the current flows through both coils in the same direction. This winding results in a uniform magnetic field between the coils with...
In an electrostatically tunable parallel plate capacitor, the distance between the two plates can be modified by a spring, as the applied voltage changes. For a given voltage difference between the plates, the distance of the two...
A vessel traveling on the surface or under water gives rise to detectable local disturbances in the Earth’s magnetic field. These disturbances can be used to trigger weapon systems. The magnetic signature of a ship can be reduced by...
This model is a static 3D simulation of a generator having a rotor with permanent magnets. The center of the rotor consists of annealed medium carbon steel, which is a nonlinear ferromagnetic material that is saturated at high magnetic...
Power inductors are a central part of many low-frequency power applications. They are, for example, used in the switched power supply for the motherboard and all other components in a computer. Computer simulations are necessary in the...
RFIDs are used in a multitude of applications such as tracking or identifying consumer products and their packaging. An RFID system consists of two main parts: A tag or transponder with a printed circuit-board (PCB) antenna A reader...
This is a model of a loudspeaker of the dynamic cone driver type, common for low and medium frequencies. The model analysis includes the total electric impedance and the on-axis sound pressure level at a nominal driving voltage, as...
Just like optical lenses focus light, electric and magnetic lenses can focus beams of charged particles. Systems of magnetic quadrupole lenses find a common use in focusing both ion and particle beams in accelerators at nuclear and...
In this model, a rotor with permanent magnets and a nonlinear magnetic material rotates within a stator of the same magnetic material. The generated voltage in windings around the stator is calculated as a function of time. COMSOL...
Estimating center-of-mass coordinates and the spatial extent of iron-rich layers helps decrease the cost of exploration. Magnetic prospecting is applicable for doing this for certain types of iron ore deposits. Passive magnetic...
