In this work we present the optical and thermal analysis of metallic nanoantennas operating at infrared wavelengths, this study is performed by numerical simulations using COMSOL Multiphysics. Several different nanoantenna designs were analyzed including dipoles, bowties and square spiral antennas. Results show that metallic nanoantennas can be tuned to absorb electromagnetic energy at infrared wavelengths, and that numerical simulation can be useful in optimizing the performance of these types of nanoantennas at optical and infrared wavelengths. 978-162841728-9 10.1117/12.2188597 https://hdl.handle.net/20.500.14352/24881 http://dx.doi.org/10.1117/12.2188597 http://proceedings.spiedigitallibrary.org/proceeding.aspx?articleid=2437030 Analysis of metallic nanoantennas for solar energy conversion
