Fourier Transform Interferometer for Ultrasensitive Terahertz Spectroscopy

PI在利用THz共振偶极子纳米天线获得强局域化和高场增强方面取得的最新结果表明，这种结构可能会应用于一类新型的THz器件。与已报道的可见光区类似，我们建议利用这些天线的独特性质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。由于初步数值模拟预期这些新工具的出色表现，申请人预计将对研究界产生重大影响，并将在更多应用部门得到迅速和广泛的传播。出于这些原因，PI最近建立了一个强有力的研究计划，旨在研究增强的太赫兹辐射-物质相互作用，这与他在太赫兹科学方面公认的专业知识非常匹配。

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.
