METHOD FOR ENHANCING PENETRATION PROPERTY OF WAVE AND APPARATUS FOR PERFORMING PREVIOUSLY SET FUNCTION BY INTRODUCING WAVE INTO RANDOM MEDIUM

摘要

The present invention relates to a method for enhancing the penetration property of a wave and an apparatus for performing a previously set function by introducing a wave into a random medium. The method for enhancing the penetration property of a wave according to the present invention comprises the steps of: (a) generating a plurality of waves each having a random phase; (b) grouping the plurality of waves randomly into a first group and a second group; (c) fixing the phase of the waves in the first group and changing the phase of the waves in the second group, and introducing same into the random medium; (d) measuring the strength of the overlapping waves of the first group and the second group which have penetrated the random medium corresponding to the change in phase of the waves of the second group; (e) extracting the phase corresponding to highest measured strength due to the phase change from among the measured strengths in step (d); and (f) adjusting the phase of the waves in the second group on the basis of the phase extracted in step (e). Accordingly, just by measuring the strength of the wave at the wavefront along which the wave penetrates, the depth of penetration can be increased from the reduction in reflection.
