Photonic crystal! Just one which guides photons of about a metre wavelength. Which is ultra high frequency radio. Actually i am not sure what the refractive index of concrete is. This is about the height of physics humour and it is just crumbling like a welsh cheese when i start to think about it. The point is that they are drilling lots and lots of very deep holes right outside my office and the noise is driving of batty so if i want to make strange allusions to structures which hardly anybody will understand then i damn well will. WHO IS GOING TO STOP ME?
