Abstract
ABSTRACT An optical modality to sense a uid by exploiting Dyakonov Tamm(DT) waves was devised. In the modality, theuid is present on both sides of the guiding interface. Theo ry showed that the angular location of reectance dipin a practically implementable conguration will shift if the refractive index of the uid changes. Furthermore,the detection sensitivity will decr ease as the refractive index of the uid increases over a wide range, andshould be comparable to that for sensing modalities that exploit surface-plasmon-polariton (SPP) waves. Highersensitivities are available with DT waves than with SPP w aves, and the DT-wave-based sensor should be simplerto fabricate than the SPP-wave-based sensor. Multiple DT waves are excitable at the same frequency, leadingto multiple channels for more reliable sensing as well as for sensing multiple analytes simultaneously.Keywords: Bruggeman formalism, Dyakonov Tamm wave, endocrine disruptor, optical sensing, prism-coupledconguration, surface-plasmon-polariton wave
