    • A THz system has a housing configured to minimize both external noise and internal stray THz waves. The housing material is selected according to the frequency range of THz waves to be propagated though the space enclosed by the housing. In general, the housing is made of foam material, such as low relative dielectric constant foam material, especially foam with conductive additives. The relative dielectric constant of foam material is usually approach to 1.0, which may minimize the reflection of THz waves propagating into the housing. The conductive additives may increase the absorption of the THz waves, even other electromagnetic waves, inside the housing. Clearly, by using proper material, such as Expanded Polypropylene (EPP) and/ or Styrofoam, with proper conductive additives, such as graphite, carbon, sliver, absorptive particles/ dyes, the housing may minimize the interference of undesired stray terahertz-gigahertz waves, even other noise.
    • 太赫兹系统具有被配置为最小化外部噪声和内部杂散THz波的外壳。 根据THz波的频率范围来选择外壳材料,以通过外壳所包围的空间传播。 通常,壳体由泡沫材料制成,例如低相对介电常数泡沫材料,特别是具有导电添加剂的泡沫。 泡沫材料的相对介电常数通常接近于1.0,这可以使传播到壳体中的THz波的反射最小化。 导电添加剂可以增加壳体内部的THz波,甚至其他电磁波的吸收。 显然,通过使用合适的材料,例如膨胀聚丙烯(EPP)和/或聚苯乙烯泡沫塑料,以及适当的导电添加剂如石墨,碳,银条,吸收性颗粒/染料,外壳可以将不希望的杂散太赫兹 - 千兆赫兹波 ,甚至还有其他噪音。

    • Devices and methods are provided for a nanocomposite having a phase change polymer matrix and conductive nanoparticles to provide greatly enhanced responsivity to temperature and/or humidity. A sensing film includes carbon nanotubes (CNTs) and the polymer. Operation near the transition temperature increases the TCR by over an order of magnitude, thus providing a new platform for devices such as IR sensors, bolometers and imaging elements, MEMS devices, compensating or uncompensated circuit elements and other electronic devices. Nanocomposite films may be under about one micron thick, and coatings, constant environment chambers or mounts, and other engineered improvements and variations may be provided to further enhance the response, range, response times or sensitivity of the film-based devices. One embodiment employs a nanocomposite film under one micron in thickness to operate as an uncooled but highly sensitive infrared bolometer under ambient conditions.
