Abstract
A method of enhancing transmittance of waves according to the invention comprises the following steps: (a) generating a plurality of waves each of which has random phase; (b) grouping randomly the plurality of waves into a first group and a second group; (c) introducing the waves onto a disordered medium by fixing phase of waves constituting the first group and varying phase of waves constituting the second group; (d) measuring intensity of the waves based on overlapped waves of the first group and the second group which penetrated the disordered medium according to the phase variation of waves constituting the second group; (e) obtaining phase having the maximum intensity according to the phase variation among intensities measured at the step (d); and (f) adjusting phase of the waves constituting the second group based on phase obtained at the step (e).
