QUASICRYSTALLINE STRUCTURES AND USES THEREOF
First Claim
1. The method of using a quasicrystalline composition of matter to produce a device, said method comprising:
- a) providing a quasicrystalline composition comprising dielectric material elements;
b) arranging said material elements such that said quasicrystalline composition has at least a five-fold symmetry axis and not a six-fold symmetry axis; and
c) selecting said material elements such that said composition is a dielectric heterostructure that exhibits a photonic band structure of corresponding symmetry, forbidden in crystals and characterized by a complete band gap, so as to produce a device comprising said quasicrystalline composition.

Abstract
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.
