It has been shown that a finite difference implementation of wave propagation can be expressed as a deep neural network (e.g., [1]). These networks can have thousands of layers and yet I don't think they suffer from the exploding/vanishing gradient problem, which I imagine is because in the physical system they model there are conservation laws such as conservation of energy.
