Electromagnetic Spiral Concentrators
A Broadband and omnidirectional electromagnetic wave ...
We present the first realized threedimensional (3D) practical implementation of the so called "optical black hole" in microwave frequencies, an electromagnetic (EM) concentrator. The 3D EM wave concentrator was designed with nonresonant gradient index (GRIN) 3D woodpile photonic crystals (PCs) structure in metamaterial regime, and fabried by Stereolithography (SL) process.

The technique of applying forminvariant, spatial coordinate transformations of Maxwell's equations can facilitate the design of structures with unique electromagnetic or optical functionality. Here, we illustrate the transformationoptical approach in the designs of a square electromagnetic cloak and an omnidirectional electromagnetic field concentrator.

Magnetic Flux Concentrator | MELTING
In order to reduce the effect of exposure to the electromagnetic fields a new legislation was finally introduced in Europe : the European directive 2004/40/CE, then modified by directive 2008/46/CE, was introduced in 2013. These regulations fix the limit values of electromagnetic fields generated by industrial machines as the induction melting plants and the employer is obliged by national law ...
