PIMS Postdoctoral Colloquium: Jun Kitagawa

The reflector antenna problem is the problem of constructing a reflective surface which directs a specified energy distribution (i.e. light, or radio signals) emanating from the center of a sphere to another specified energy distribution on the so-called far-field sphere. I will discuss some of the basic analytic and geometric background of this problem, and a connection that has been discovered in recent years to Monge's optimal mass transportation problem.
