Abstract

In an ocean of uniform depth the propagation of small-amplitude plane waves is impeded by two vertical semi-infinite perfectly reflecting barriers extending from the bottom of the sea to above the free surface. The two screens do not lie in general in the same plane, and they are separated by a gap through which wave energy is transmitted from the open sea into the sheltered region. A transmission coefficient is established for small gap widths relative to the wavelength and the agreement with existing theoretical results for special cases is found to be very good.
