Basically, the Max Planck Institute and Ludwig Maximilian University in Germany have found that dielectrics, using very short bursts ... if that gives you a better idea of the scale. A single wave of ...
Dielectrics and electric polarisation ... and their magnifying powers. Chapter–10: Wave Optics Wave optics: Wave front and Huygen's principle, reflection and refraction of plane wave at a plane ...
Imagine a sine-wave generator attached to a wire that creates a time-varying ... Michael Faraday noticed that when dielectrics (insulators) are placed in the gap between the plates of a parallel-plate ...
Early metamaterials included so-called artificial dielectrics, composed of centimeter-scale arrays of metallic particles, that were capable of guiding and focusing radio waves like a dielectric 6. In ...

The team developed an approach using photonic crystals. The Science of Invisibility Becoming ... objects by using multilayer coatings formed from ordinary dielectrics. In order to suppress wave ...
This project aims to develop and analyze efficient numerical methods for forward problems in the time domain involving the propagation and scattering of electromagnetic waves in complex dielectric ...
Future terahertz-wave devices for communications and imaging could benefit from a lens based on artificial dielectrics. Terahertz radiation (about 100 to 10,000 GHz) is a relatively unexplored slice ...
By using a single layer of these dielectrics and changing the height of the ceramic particles, the scientists were able to specify how the light waves were reflected. While we aren’t quite ready for ...
Later, they proposed another approach to cloaking objects by using multilayer coatings formed from ordinary dielectrics. In order to suppress wave scattering from a cloaked object, they optimized the ...
There are three basic types of solids: metals, semiconductors, used in today's transistors, and insulators – also called dielectrics. Dielectrics do ... of 1 femtosecond – the same time as the light ...
