Abstract

The optical properties of Microcellular Polyethylene Terephthalate (MCPET) towards light and terahertz waves were compared. Within the measurement range of 0.3–1.3 THz and 30 K to room temperature, the refractive index remained nearly constant at approximately 1.15, close to 1. It was observed that MCPET with a thickness of 0.5 mm transmits over 70% of terahertz waves, while blocking more than 99.9% of light in the 300–2000 nm range. These findings present significant advantages for the design of optical devices using MCPET, highlighting its potential for selective dichroism and high opacity in specific applications.

微孔聚对苯二甲酸乙二酯 (MCPET) 在宽温度范围内的太赫兹特性分析

比较了微孔聚对苯二甲酸乙二酯（MCPET）对光波和太赫兹波的光学特性。在 0.3-1.3 太赫兹和 30 K 至室温的测量范围内，折射率几乎保持恒定，约为 1.15，接近 1。这些发现为使用 MCPET 设计光学设备提供了显著优势，突出了其在特定应用中的选择性二色性和高不透明性潜力。

期刊介绍： The Journal of Infrared, Millimeter, and Terahertz Waves offers a peer-reviewed platform for the rapid dissemination of original, high-quality research in the frequency window from 30 GHz to 30 THz. The topics covered include: sources, detectors, and other devices; systems, spectroscopy, sensing, interaction between electromagnetic waves and matter, applications, metrology, and communications. Purely numerical work, especially with commercial software packages, will be published only in very exceptional cases. The same applies to manuscripts describing only algorithms (e.g. pattern recognition algorithms). Manuscripts submitted to the Journal should discuss a significant advancement to the field of infrared, millimeter, and terahertz waves.
