Optical properties of gold nanorods macro-structure: a numerical study

摘要: In this contribution, a numerical study of the optical properties closely-packed gold nanorods was performed. The studied nano-objects are experimentally grown on tilted polydimethylsiloxane (PDMS) substrate by using physical vapor deposition (PVD). This method creates to certain angle with respect normal. geometry allows exciting both transverse and longitudinal modes rods. As demonstrated in previous experimental work, such PVD-grown show promising possibilities as strain gauges or strain-tunable metamaterials if fabricated stretchable dielectric substrate. is based data from work pushes further subject approaching an optimized nano-structure allowing better strain-sensitivity (particularly changing auto-organization said nanorods).
