Abstract:In this work, a nano-cavity based metal-insulator-metal (MIM) structure is proposed which can be used as a high-performance refractive index sensor. The analysis of its sensing capabilities is done by determining the transmission characteristics of light through the insulating air channel between the metal layer The loss in transmission in this channel is indicative of light leaking out of it and portion of it getting coupled to nano-cavities considered in the metal layers on both sides of air channel. The ana… Show more
