An umbrella-like approach for design of crystals with specified properties

چکیده
In the product design area, the major concern is how to obtain the desired product requirements in a physically possible and economical process way. A reverse engineering based approach is proposed here for the generation of possible process alternatives applied to crystallization area, in order to obtain desired crystal features. The called umbrella-like approach integrates thermodynamics and crystallization kinetic data to compose a tool able of generating and analyzing suitable operating strategies to obtain tailor made crystal products. New process alternatives can be generated and improved alternatives of existing ones can be analyzed, providing insights to product and process design tasks. The direct approach can be then utilized in order to completely design the process.

A Systematic Approach to Photonic Crystal Based Metamaterial Design
Photonic crystal design procedure for negative refraction has so far been based on trial and error. In this paper, for the first time, a novel and systematic design procedure based on physical and mathematical properties of photonic crystals is proposed to design crystal equi-frequency contours (EFCs) to produce negative refraction. The EFC design is performed by the help of rectangular stair-c...
