Abstract: Light transmission through an array of tunnel-coupled channel waveguides is studied in detail. It is shown that a discrete structure of the light-transmitting medium leads to a modification of the law of light refraction. It is also shown that a new type of total internal reflection of light inside the structure manifests itself in an inhomogeneous array of coupled waveguides. The process of light propagation in an array of identical channel waveguides, which are arranged equidistantly along concentric circles, is investigated. It is established that such a waveguide array is equivalent to an inhomogeneous system of coupled waveguides. The mode excitation process in an array of ring channel waveguides located on cylindrical and conical surfaces is considered.
