History

*Maxwell's original piece in the Cambridge and Dublin Mathematical Journal for Feb.

1854 is most easily found in his collected works, Ed. W. D. Niven, The Scientific Papers

of James Clerk Maxwell, vol. 1, pp 76 - 79 [CUP 1890].

Composites

Why ?

• New design techniques, e.g. transformational EM

• Freedom from traditional shape/volume consideration

How?

Design of novel materials and processes

- inclusions with wider range of EM properties

- techniques to disperse the inclusions within 2PhM

- scalable and low cost manufacturing methods

- multimaterials processing

• Cost reduction to a few ~10s £

• Volume manufacture, 10s of thousands

• Integrated with system

• Parameter space trade-offs

• Tunable materials options

QQ approach : stimulate R&D and move to high TRL systems

: early exploitation

: partnerships
