Mahbubuzzaman; Sanjoy Sarker; Mahdy Rahman Chowdhury; 1620799043; 1620531043Reversal of the optical binding force is one of the fastest growing and auspicious area of optical manipulation. We used optical manipulation to find the reversal optical binding force. Until now optical manipulation was used to find reversal in far field. Two counter propagating plane waves were used on sphere shaped dielectric and plasmonic nano dimers. In our setup we used plasmonic substrate in some cases to get strong reversal of binding force. We kept the dielectric and plasmonic nano dimers in air medium and in one of our setups we polarization of dielectric (Y polarized) and plasmonic (Z polarized) were different. Our study provides a sturdy approach to gain a reversal of optical binding force using plane light wave. The optical binding forces we got were immensely sensitive to inter particular distance.
