Quasicrystalline structures and uses thereof
This invention relates generally to the field of quasicrystalline structures. In preferred embodiments, the stopgap structure is more spherically symmetric than periodic structures facilitating the formation of stopgaps in nearly all directions because of higher rotational symmetries. More particularly, the invention relates to the use of quasicrystalline structures for optical, mechanical, electrical and magnetic purposes. In some embodiments, the invention relates to manipulating, controlling, modulating and directing waves including electromagnetic, sound, spin, and surface waves, for pre-selected range of wavelengths propagating in multiple directions.
1. A material comprising first and second quasicrystalline patterns, each pattern comprising locations, said material comprising a plurality of refractive indices wherein said plurality refractive indices have a plurality of maximum values and a plurality of minimum values and wherein said plurality of maximum values are at locations in a first pattern that is quasicrystalline and said minimum values are at locations in a second pattern that is quasicrystalline, wherein said first pattern is quasicrystalline in three-dimensional space and wherein said material comprises a complete bandgap.
2. The material of claim 1 , wherein said plurality of refractive indices further comprises a plurality of medium values at locations in a third pattern that is quasicrystalline.
3. The material of claim 1 , wherein said first pattern produces an icosahedral shape.
