Title: Complex medium having selectable electromagnetic transmitting characteristic
Inventor: MANFURETSUDO AARU KUEENRU
IPC: H01L31/0384
Filed: 1994-10-28
Abstract: PURPOSE: To provide a radiation-absorbing material which is suitable for manufacturing a package, a sheet, ink, paint, a decorative surface treatment agent, lotion, cream, and gel. CONSTITUTION: This composite medium exhibits a constant optical property which gives complete radiation absorption, covering a selected bandwidth, with reference to equal, and globular, and nano size of particles. One type of the particles shows 'absorption end' in a selected wavelength, and the wavelength transmits the radiation over a property band gap wavelength, on the other hand it effectively absorbs all the radiation of the smaller wavelength than the minimum value. The other types of particles show 'optical resonance' and radiate property wavelength, and interact with the particles and gives rise to self-reinforcing internal reflection to strongly raise the amplitude of the radiation captured within the particles.
