Abstract: Disclosed herein are a junction structure for wave propagation and a wave diode and a wave half-adder using the same. According to the present invention, the junction structure for wave propagation permits selective coupling of waves propagating through a junction plane between different wave propagation structures, whereby the wave junction structure, wave junction diodes and wave half-adders using waves including photons, surface plasmons, optomechanical phonons and their composite waves are realized to provide the same functions as those of electrical junction structures and application devices thereof.
