This kind of thing is starting to happen, albeit in a small way: The Loc8tor uses so-called Radio Frequency Identification or RFID tags, small, flat components that usually include an integrated circuit and an antenna, and that are designed to allow companies to track inventory just by passing goods close to a reader.

如今这类事情已经出现了苗头，尽管还只是发生在小范围。Loc8tor使用了一种名为射频识别的标签，这个小部件通常由集成电路和天线组成，企业可以用它来监测库存情况，只要把货品靠近阅读器便可以获取信息。

The system consists of radio frequency band pass filter, local oscillator and sub-harmonic mixer.

文中对构成电路的鳍线及其不连续性和构成系统的三个部分分别做了研究。

In our experiments, the hafnium films were deposited on molybdenum substrates by radio frequency magnetron sputtering technology, and the barium oxide layers were prepared by the chemical method to simulate the grid structure of traveling wave tubes. Then, the surface phase and compositional change in the grid was studied under high temperature by annealing from 900K to BOOK, which can be used in explaining the suppression mechanism of hafnium film.

实验中，利用射频磁控溅射技术在Mo基底上制备了Hf膜，并利用化学方法制备了BaO涂层以模拟行波管栅极结构，随后在N_2保护下，通过在900K到1300K范围内退火，研究栅极处于高温工作环境下表面相结构和成分的变化，以此解释了Hf薄膜抑制栅极电子发射的工作机理。
