Plasmonic Antennas based Gas sensor using Graphene

چکیده
Plasmonics based sensors have been a prominent area of research. Plasmonics based sensors are widely used in bio sensing and many other applications. The basic mechanism in which these sensors operate is that there are metal nano particles that are separated by a very small distance between them. The dimensions of these nano particles is much smaller than the incident light [1]. For sensing purposes, we use the light in the visible spectrum. The dimension of those nano particles is in the range of 20200nm [2]. When light is incident on these nano particles, it generates a very high electric field in the gap between the two nano particles. This generated electric field is dependent on the size, shape and material of the nano particles and also the properties of the environment surrounding the nano particles.
