Abstract: Disclosed is a single-ended test method for the wave-absorbing characteristic of a material. The device comprises a sample cavity, a microwave transmission rod, spring needles, an SMA joint and a vector network analyzer, wherein one end of the sample cavity is provided with a test fixture; the microwave transmission rod is arranged in the sample cavity and is connected with the test fixture in a penetrating mode; the spring needles are arranged in the microwave transmission rod; the SMA joint is arranged at the other end of the sample cavity; the receiving end of the vector network analyzer is electrically connected with a coaxial cable, and the other end of the coaxial cable is electrically connected with the other end of the SMA joint.

Abstract: An anti-counterfeit banknote recorder, an automatic teller machine and a system are provided. The recorder includes a microprocessor, a memory, a communication module and a first photographic device. The first photographic device includes a camera and a flasher with different types of rays. The microprocessor is able to regulate the flashlight automatically so as to provide different types of rays according to the optical characteristics on the surface of the banknote under monitoring, and control the camera so as to take photos of the banknote under monitoring, thus, photo information of the banknote is obtained. The microprocessor is able to receive commands from the external equipments via the communication module, thus, the first photographic device is controlled accordingly so as to take photos. Moreover, via the communication module, the microprocessor is able to receive transaction information in relation to the banknotes under monitoring from the external equipments.
