    "abstract": "The basic equations governing propagation of electromagnetic and\ngravitational waves in vacuum are nonlinear. As a consequence photon-photon\ninteraction as well as photon-graviton interaction can take place without a\nmedium. However, resonant interaction between less than four waves cannot occur\nin vacuum, unless the interaction takes place in a bounded region, such as a\ncavity or a waveguide. Recent results concerning resonant wave interaction in\nbounded vacuum regions are reviewed and extended.",
