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...
A scanning electron microscope samples images by scanning a target with a high-energy beam of electrons. The subsequent electron interactions produce signals such as secondary and back-scattered electrons that contain information about...
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...
The development of mixers does often not only have to account for effectiveness, but also other factors must be involved, such as cost and complexity for manufacturing. The three models study a laminar static micro mixer with two parallel...
The dipole antenna is one of the most straightforward antenna configurations. It can be realized with two thin metallic rods that have a sinusoidal voltage difference applied between them. The length of the rods is chosen such that they...
Inductors are used in many applications for low pass filtering or for impedance matching of predominantly capacitive loads. They are used in a wide frequency range from near static up to several MHz. An inductor usually has a magnetic...
Permanent magnets with a one-sided flux have many uses. The one-sided flux behavior is obtained by giving the magnet a magnetization that varies in the lateral direction. This model shows this technique to model a cylindrical one-sided...
Photonic crystal devices are periodic structures of alternating layers of materials with different refractive indices. Waveguides that are confined inside of a photonic crystal can have very sharp low-loss bends, which may enable an...
This model simulates deposition of silicon onto a wafer using a 95/5 mixture of argon and silane. The plasma chemistry consists of 19 volumetric reactions, 8 surface reactions, 11 volumetric species and 3 surface species. The plasma is...
In every system where there is conduction of electric current, and where the conductivity of the material is finite, there will be electric heating. Electric heating, also referred to as Joule heating, is in many cases an undesired...
