Abstract
To investigate the behaviour of scalar focus wave modes through a lens, we
discuss their propagation in a square law medium with the refractive indice
s n(r) = n(0) + n(1) cos(beta r), r(2) = x(2) + y(2). We get an explicit so
lution of the wave equation in the region beta r much less than 1.
