Abstract Details

2017, Master of Science (MS), Wright State University, Physics.
In the phenomenon known as extraordinary optical transmission (EOT), a narrow band of selected frequencies are transmitted when incident on an array of subwavelength periodic apertures where the resonant frequency is determined by the geometry of the array of apertures and optical properties of the metal-dielectric interface. This takes place due to the excitation of surface plasmon polaritons (SPPs) at the metal and dielectric interface. Using the COMSOL Multiphysics software RF Module, a unit cell of a carbon nanotube (CNT) based EOT device is modeled in order to verify theoretical calculations of the resonant frequency using S-parameter calculations. The simulation of the interaction of the THz light with the CNT EOT device exhibits a resonant transmission at 235 GHz. Further, the transmission falls exponentially with increasing device thickness of the device, and the transmission peak reaches its maximum value at the skin depth. Although some of the transmission features, such as Wood’s anomalies, are seen in the modeled device only, the other numerical results show good agreement with the experimental observations reported in literature. The fabricated single-walled carbon nanotube devices with 100 nm thickness do not indicate any resonances; however any such resonances might be weak due to the thin nature of the samples.
