Metamaterials are a new and emerging technology with vast potential to reshape our views on what is and isn’t possible in this physical world of ours. Unlocking the mysteries and overcoming the obstacles associated with metamaterials would lead to a host of technological advances once thought impossible by even the most imaginative of individuals. From making computer chips smaller and faster than the most advanced current ones, to protecting structures from earthquakes, to developing imaging technology that doesn’t harm tissue […]

Today, guest blogger and Certified Consultant Nagi Elabbasi of Veryst Engineering shares simulation research designed to optimize band gaps for phononic crystals. Phononic crystals are rather unique materials that can be engineered with a particular band gap. As the demand for these materials continues to grow, so does the interest in simulating them, specifically to optimize their band gaps. COMSOL Multiphysics, as we’ll show you here, can be used to perform such studies.

A team of researchers from the Karlsruhe Institute of Technology in Germany has figured out a new simple mathematical technique for designing mechanical cloaks. This type of cloaking has great potential for practical uses, such as protecting buildings from earthquake damage for example.

What is the relation between the extremely popular band One Direction, quantum mechanics, and cosmology? Stephen Hawking may just have explained this relation in one of his recent talks at the Sydney Opera House. It has to do with the prediction of parallel universes, where we, in an infinite number of worlds, could find worlds that are almost identical to ours but with all possible permutations and differences, much like the 410-page books in The Library of Babel by Borges.

Previous work on cloaking for flexural waves in elastic plates presented limitations and near invisibility. Now, a research group in Europe has figured out a new theoretical framework to both overcome the limitations and achieve exact cloaking for flexural waves in Kirchhoff-Love plates. To visualize and test the quality of the cloak, they ran COMSOL Multiphysics simulations.

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.
