Research Field

Microwave reflection imaging using a magnetic tunnel junction based spintronic microwave sensor

Applied Physics Letters (2012)

Lei Fu Zhong Cao Simon Hemour Ke Wu D. Houssameddine

A far-field microwave imaging technique has been developed using a spintronic sensor based on a magnetic tunnel junction (MTJ). Such a sensor can directly rectify a microwave field into a dc voltage signal using the Seebeck effect. Thanks to the high conversion efficiency of the microwave rectification in MTJs, the microwave power sensitivity of the spintronic sensor is on the order of 1–10 mV/mW. This high sensitivity allows the sensor to directly measure the coherent spatial scattered microwave field distribution, which gives it the ability to non-destructively detect hidden objects down to a few wavelengths in size.

In this paper, based on bidirectional optical amplifiers and n couplers, we propose a bidirectional transparent (BTL) network configuration. Compared to the MPL and SLB schemes, the BTL structure can save much optical fiber and optical filters.

Nondestructive two-dimensional phase imaging of embedded defects via on-chip spintronic sensor

Applied Physics Letters (2012)

Zhong Cao Michael Harder Lei Fu Bin Zhang Wei Lü

A microwave near field phase imaging technique has been achieved by an on-chip spintronic sensor. The sensor directly rectifies a microwave field into a dc voltage signal by employing the spintronic principle, in which the relative phase between microwave electric and magnetic fields plays an important role. By manipulating the relative phase, the sensor can nondestructively detect embedded defects of subwavelength size.

Bidirectional Active Bus and its Applications in Fiber Networks

Journal of Optical Communications (1996)

Zhong Cao Jian-en Guo Ling Li Peida Ye

Based on π couplers and optical amplifiers of two-way amplifications, we propose a Bidirectional Active Bus (BAB) structure for fiber networks which support two-way communications. The BAB structure at least saves half amount of bus fiber and optical amplifiers than the Dual Active Bus scheme [1, 2]. The structure applies to both single-optical-carrier and optical FDM/WDM fiber networks. In expanding/interconnecting fiber networks, the proposed BAB structure is free of Signal Circulation (SC) [3, 4] and Multipath Propagation (MP) [5] problems and independent of constellation of sub networks, and it uses less amount of fiber and optical filters than the MPL and SLB schemes [3, 4]. Star-BAB structure is suggested for large networks. The BAB structure has potential good survivability.

Analysis of the line shape of electrically detected ferromagnetic resonance

Physical Review B (2011)

Michael Harder Zhong Cao Y. S. Gui Xiaolong Fan C.‐M. Hu

This work reviews and examines two particular issues related with the new technique of electrical detection of ferromagnetic resonance (FMR). This powerful technique has been broadly applied for studying magnetization and spin dynamics over the past ten years. The first issue is the relation and distinction between different mechanisms that give rise to a photovoltage via FMR in spintronic devices, and the second is the proper analysis of the FMR line shape, which has become the ``Achilles heel'' in interpreting experimental results, especially for either studying the spin pumping effect or quantifying spin Hall angles via the electrically detected FMR.

SIMULATION OF STATIC SURFACE STATES IN AlGaN/GaN HEMT INCLUDING HOT ELECTRON AND QUANTUM EFFECTS

International Journal of Modern Physics B (2012)

Hui Xia Xiao-Dong Wang Zhong Cao

Two-dimensional simulations of hot electron and quantum effects in AlGaN / GaN HEMT devices are performed. The effect of surface states is accounted for by defining effective net surface charges in our simulation. Simulation results show that surface states and surface traps which model the electron depletion play an important role in the electrical characteristic of AlGaN / GaN HEMT. Hot electrons play an important role in the charge transport by spilling over into the bulk GaN where they are captured by traps. Excessive net surface charges make the 2DEG much hotter through the role of vertical electric field above the channel. Lattice scattering and electron tunneling are enhanced with the increasing density of net surface charges, and electron mobility and saturation velocity are significantly reduced.

This paper describes the prototyping of a broadband multiple input multiple output (MIMO) wireless testbed using a new system level design methodology. First, the layout of the MIMO wireless testbed is introduced. Then, the advantage of the proposed methodology, which integrates the system design and hardware implementation, is discussed. A MIMO channel sounding system is presented as an example to show the efficiency of the new methodology.
