Metamaterial

myminifactory

This is a material which have particular effect to wave. Because of it periodic structure, it can conduct water and make wave avoid the central circle. It's a new type of material currently discovered, named Metamaterial. Find more information on internet or ask me some question I've done a conference about it. The metamaterial is effective for small wave, and must be printed a full scale. (It's pretty long but it won't work otherwise)
