Perhaps if we can outfit submarine hulls with two layers instead of one, we might be able to cancel out the reflected waves. I have already measured out how thick the gap between the hulls should be: x(lambda)/4; where x is any odd integer. In this way, we will recieve reflection where the waves have the least energy, which is at the equilibrium. The first layer should be any kind of material able to transmit 66% of wave energy and reflect 33%. 66% of the wave energy is transferred...
