Wave propagation through a set of slits

Regular Paper


Propagation of a wave through a set of identical slits is investigated using a scalar diffraction theory. The slits are aligned on a straight line with equal spacing. The asymptotic expansion of the matrix elements of the propagation operator is derived and compared with numerical calculations. And then the eigenmodes and eigenvalues of the propagation operator are estimated. Our analysis should provide an insight into the properties of waveguides composed of opaque masks that have been proposed recently.
