This invention relates generally to the field of quasicrystalline structures. In preferred embodiments, the structure is heterostructure comprising dielectric materials arranged in two-dimensional space such that the overall structure is more rotationally symmetric than periodic structures. Symmetry may be five-fold or greater than six-fold. Such higher rotational symmetries provide stopgaps in nearly all directions. 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 a pre-selected range of wavelengths propagating in multiple directions.
