The failure of ?classic? perturbation theory at a rough Neumann boundary near grazing.

Rice's (1951) ?classic? perturbation theory predicts an erroneous limit at grazing for vertically polarized plane wave scatter from an infinite perfectly conducting rough surface; likewise, the attendant result for the specularly reflected mode also fails at grazing. We show where and why in th...
