Optical sub-diffraction limited focusing for confined heating and lithography
… studied to be used as near field transducers for heat-assisted magnetic recording. They have the capability of transmitting and confining enough energy to increase the temperature of a recording medium without reaching detrimental temperatures themselves. Numerical methods are presented to prove …
