In this paper, near-field antenna probe is designed for propagating spin wave spectroscopy (PSWS) measurement. We compare the meander-line and straight-line antenna probes. Effect of the dimension parameters of antenna probe on scattering parameter is investigated. Near-field distribution and radiation pattern of these two kinds of antenna probe are discussed. Also, the placement of antenna probe...
In this paper, we investigate the propagation characteristics of spin electromagnetic wave (SEW) in ferromagnetic film. We calculate the amplitude and phase distribution of spin wave along propagating direction for MSSW mode and BVMSW mode. Two kinds of antenna probes are considered. And we simulate the amplitude and phase distribution of magnetic field around the antenna probe.
This paper describes a polarimetric information extraction method using PolSAR data. The proposed method is based on the covariance matrix and intended to be applicable to the general nonreflection symmetric scattering case that the copolar and cross-polar correlations are not close to zero. Asymmetric scattering term, which can entirely represent the asymmetric information of PolSAR data, is proposed...
This article introduces a type of embedded MCU network measure and control system based on Ethernet, which adopts high speed MCU with kernel of 8052. Through controlling the special chip for Ethernet, the system realized the function of TCP/IP protocol. Since the system can be used as a independent system, any computer on the net can control the system or transmit order and data to the system through...
We demonstrate the piezoelectric effect on the responsivity of a metal-semiconductor-metal ZnO micro-/nanowire photodetector. Piezo-phototronic effect can enhance the detection sensitivity more than fivefold for pW levels light detection.
