Propagation of OPC light is modeled in two stages: (a) Forward scenario: a CW light source embedded at the center of a 40-μm-diameter empty region centered inside a scattering medium consisting of 630 randomly-positioned (minimum edge-to-edge spacing of 0.5 μm), 10-μm-diameter dielectric (n = 1.6) cylinders. (b) Playback scenario: amplitude and phase of the CW outgoing wave is recorded and phase-conjugated to form a circular wavefront converging through the scattering medium.
