NONLINEAR WAVE REFLECTION FROM A SUBMERGED CIRCULAR CYLINDER

The paper discusses analytically the nonlinear wave reflection caused by a circular cylinder, submerged under a free surface in water of infinite depth. For monochromatic incident waves it is shown that there is no reflection of order m and frequency mw (m integer). This means that the dominant part of the mode of frequency mw is not reflected. For bichromatic incident waves it is found that the second-order wave with 'sum-frequency' has no reflection. It is shown that the x- and y- components of the oscillatory force of order m and frequency mw have identical amplitudes and a phase-difference one halfpi. A corresponding result is also true for bichromatic waves.
