Abstract:

Work done during the relevant period fell under the following headings Lens and Antenna Design The problem here is, given two points, to design an optical lens which will have the property that it focusses all rays of light from the one point onto the other. Nonlinear Diffusion and Free Boundary Problems During this period, much of the work in nonlinear diffusion centered on the fabrication of semiconductors. In particular, Dr. J. R. King completed his thesis on the mathematical aspects of semiconductor process modelling, and he and C. P. Please wrote a paper on diffusion in crystalline silicon.
