Claim 1
Independent Claim
100 words
THE METHOD OF CONVERTING A SMOOTH DIELECTRIC SURFACE INTO A FROSTED LIGHT DIFFUSING SURFACE MICROSCOPICALLY DEFORMED BY ELECTROSTATIC FORCES INTO A PATTERN OF ALTERNATING ELEVATIONS AND DEPRESSIONS SAID ELEVATIONS AND DEPRESSIONS BEING RANDOMLY POSITIONED WITH RESPECT TO SAID DIELECTRIC SURFACE AND CHARACTERIZED AS HAVING A LATERAL SPACING OF 1-5 TIMES THE THICKNESS OF THE MATERIAL SUPPORTING SAID SURFACE, COMPRISING MAINTAINING SAID SURFACE AT AN ELECTROSTATIC POTENTIAL SUCH THAT THE LATERAL REPULSIVE ELECTROSTATIC SURFACE FORCE EXCEEDS THE SURFACE TENSION FORCE, SIMULTANEOUSLY MAINTAINING SAID SURFACE IN A VISCOUS CONDITION, AND DEFORMING SAID LAYER INTO SAID PATTERN IN RESPONSE TO SAID ELECTROSTATIC FORCES.
