Fourier Transform Interferometer for Ultrasensitive Terahertz Spectroscopy

PI最近在利用太赫兹谐振偶极子纳米天线获得强定位和高场增强方面取得的成果，为这种结构在新型太赫兹器件中的应用指明了可能。与已经在可见光谱区域报道的类似，我们建议利用这些天线的独特特性来实现纳米等离子体辅助太赫兹生物传感器和非线性器件。由于这些新工具的出色表现，通过初步的数值模拟，申请人预计将对研究界产生巨大影响，并在更多的应用领域迅速而广泛地扩散。由于这些原因，PI最近建立了一个强有力的研究计划，旨在研究增强太赫兹辐射与物质的相互作用，非常适合他在太赫兹科学方面公认的专业知识。

Recent results achieved by the PI in obtaining strong localization and high field enhancement using THz resonant dipole nanoantennas point toward the possible application of such structures for a novel class of THz devices. Similarly to what has been already reported in the visible spectral region, we propose to exploit the unique properties of these antennas for the realization of nanoplasmonic-assisted THz biosensors and nonlinear devices. Thanks to the outstanding performances of these new tools, anticipated by preliminary numerical simulations, the applicant foresees a large impact on the research community as well as a rapid and widespread diffusion in more applicative sectors. For these reasons, the PI has recently established a vigorous research program directed toward the investigation of enhanced THz radiation-matter interactions, well suited within his recognized expertise in THz science.
