An infinite circular wave originates from the center of a square and propagates outward toward its edges. Simultaneously, mirror waves are generated at the edges of the square and travel inward toward the center. The edges are perfectly reflective and non-dissipative. This configuration results in interference patterns within the square due to the interactions between the mirror waves and due to reflections. The wavelength of the wave is equal to one-fourth the length of the square's side.
The square is then topologically transformed into a horn torus by collapsing its sides to a single point and connecting them to the center of the square from opposite poles. In this horn torus configuration, mirror waves emanate from either side of the central point, traveling toward the surface and generating interference patterns.
This configuration can be extended and repeated across other dimensions.
