Electromagnetic Materials: Proceedings of the Symposium R, 3-8 July 2005, suntec Singapore International Convention and Exhibition Centre

The science of energy harvesting materials is experiencing phenomenal growth and attracting huge interest. Exploiting recently acquired insights into the fundamental mechanisms and principles of photosynthesis, it is now possible to forge entirely new and distinctive molecular materials and devise artificial photosystems and applications far remote from conventional solar cell technology. In this comprehensive treatment of energy harvesting, a team of internationally acclaimed scientists at the forefront of the subject paint a state-of-the-art picture of modern energy harvesting materials science. Covering all aspects of the subject, ranging from natural plant and bacterial photosystems, through their biologically inspired synthetic analogs, to other photoactive molecular materials such as dendrimers, the book also establishes the theory and underlying principles across the full range of light harvesting systems. With an authoritative, comprehensive and well-referenced content, it will appeal to all students, researchers and technologists interested or involved in solar energy, photobiology and photoactive materials science.

The high quality contributions reflect the principle aims of the conference : to provide an international forum for scientists and engineers to report their most recent research findings, to exchange ideas and information, and to nuture and establish research ties. Electromagnetic materials have both civilian and defence applications, such as novel antenna designs, protection against high power transients in densely packed printed circuits, and special frequency response or polarization response to meet component or system specifications. An in-depth understanding of the responses of materials to electromagnetic waves may even enable us to design and fabricate materials with properties not found in nature Offers a comprehensive treatment of energy harvesting. Covering various aspects, ranging from natural plant and bacterial photosystems, through their biologically inspired synthetic analogs, to photoactive molecular materials such as dendrimers, this book establishes the theory and underlying principles across a range of light harvesting systems.
