Significant development of femto-second lasers enables us to study atto-seconde phenomena. In this study region, there's a demand of optical-field measurement device that can be easily used. Now, we fabricated a measurement device using 'plasmonic enhancement' and 'optical field photoemission.' In last congress, we presented the results of intensity dependence, which is a positive result for field measurement. In this time, we'll present about results of more direct demonstration of field sensitivity by using anti-symmetric field.
