Magnetic Damping of a Vibrating Cantilever Beam
What happens when you place a vibrating conductive object in a static magnetic field? The magnetic field will induce a current in the moving solid and the charges moving through a magnetic field will experience a force. The resultant force acts to oppose the motion of the structure, which will lead to damping.
Happy Birthday, Michael Faraday
Michael Faraday was a famous British physicist and chemist. His remarkable contributions, particularly within electrochemistry and electromagnetism, helped pave the way for breakthroughs in modern science.
Shape-Memory Polymer May Help in Facial Reconstructions
Facial reconstruction methods are often needed to treat bone gaps that result from birth defects and injuries. At Texas A&M, researchers have developed a shape-memory polymer that has the potential to fill in critical-sized bone defects in the face, as well as allow for the growth of new bone cells.
Modeling a Complementary Split Ring Resonator with Ease
Last month, my colleague Alexandra Foley introduced an RF modeling example that uses periodic boundary conditions. Another RF model that can be created with ease by taking advantage of periodic boundary conditions is the Frequency Selective Surface, Periodic Complementary Split Ring Resonator model.
AltaSim Simulates Mie Scattering of Electromagnetic Waves
Researchers from AltaSim Technologies presented a paper at last year’s COMSOL Conference in Boston sharing their analyses on Mie scattering of electromagnetic waves and how they compare to the Mie solution.
Computing Voltages Produced by Electromagnetic Induction
When you lose power at home, you may use a shaker flashlight to navigate about your house. This type of flashlight relies on voltage produced by electromagnetic induction in order to be powered. How much voltage can one of these flashlights produce, do you think? Here, we find out through computation, using the AC/DC Module.
Simulating the Focusing Effect of Magnetic Quadrupoles
If you walked into a particle or nuclear physics center, like the world-renowned CERN, you may come across a magnetic quadrupole lens (after security clearance, I would imagine). Here, we’re going to discuss what magnetic quadrupole lenses are and study the focusing effect three consecutive quadrupole assemblies have on B5+ ions traveling through such a lens.
Shaping Crystals for Camouflage Surfaces
A recent discovery indicates that certain particles can be drawn into crystalline structures through the controlled use of ultraviolet light and chemistry. This discovery can eventually lead to the possibility of creating color-changing surfaces and materials for reasons of dynamic camouflaging.
