When compared with the traditional materials, the advantages of composite materials are high strength, stiffness, lightweight, heat resistance, moisture resistance, chemical and corrosion resistance to aggressive environments, low thermal conductivity, and design flexibility.
The problem of monitoring the condition of composite material has become relevant to the development and widely used of composite materials.

Preface Optical Materials is a peer-reviewed scientific journal that publishes original papers and review articles on the design, synthesis, characterisation and applications of materials, suitable for various optical devices.
The journal also publishes papers about physical and chemical properties of such materials and their applications.
Aiming to the advances of Optical Materials and Circuit Design, 2012 International Conference on Future Optical Materials and Circuit Design (FOMCD 2012) is an annual conference to call together researchers, engineers, academicians as well as industrial professionals from all over the world to present their research results and development activities in Optical Materials and Circuit Design.
The papers come from both academia and industry reflecting the international flavor of this event in the topics of Optical Materials and Circuit Design, Material Science and Engineering, Nanomaterials Synthesis and Properties, Nano Devices and System, Nano materials, Technologies for Applications, Circuits and Systems, Mechanical Engineering, Industrial Electronics, etc.
