Temperature gradient distribution in the near field of corrugated optical tip nano antenna

This work is dedicated to the improvement of the near-field enhancement of thermal effect around gold and silver corrugated tip optical antennas. We check the coupling coefficient of the laser light to the grating of the nano antenna body. By applying circular grating to the conical plasmonic optical antenna made of gold and silver, the temperature and temperature gradient around tip will be enhanced.
