Abstract :
Terahertz waves bound inside a metallic rod-array is successfully demonstrated and used to sense ultra-thin molecular layers in the presentation. From the transmitted surface waves with constructive interference, nanometer-thick films of SiO2 and ZnO are successfully identified, corresponding to λ/1923 and superior to the available THz sensors.
