This article reviews recent advances in terahertz science and technology that rely on confining the energy of incident terahertz radiation to small, very sub-wavelength sized regions. We focus on two broad areas of application for such field confinement: metamaterial-based nonlinear terahertz devices and terahertz near-field microscopy and spectroscopy techniques. In particular, we focus on field confinement in: terahertz nonlinear absorbers, metamaterial enhanced nonlinear terahertz spectroscopy, and in sub-wavelength terahertz imaging systems.

Abstract. Terahertz technology, including terahertz spectroscopy and terahertz imaging, is gaining increasing attention and plays an important role in various fields. With the development of terahertz sources and detectors in recent decades, terahertz imaging has been applied in many fields, including security screening, material evaluation, biomedicine, agriculture, and food science. However, progress has been comparatively slow in applying terahertz imaging to agriculture and food engineering. In this article, some commonly used terahertz imaging systems are summarized, and various applications of terahertz imaging in agriculture and food engineering are reviewed, including food safety and quality inspection, seed inspection, water content evaluation of plant leaves, and others. Challenges and the future outlook of terahertz imaging are also discussed. Keywords: Agriculture, Food, Instrumentation, Seed, Terahertz imaging.
