A high-selective microstrip wideband bandpass filter (BPF) with an adjustable notched-band is proposed. First, a pair of open-ended stubs is tap-connected to a ??/2 uniform impedance resonator at two symmetrical locations with respect to its centre, and they are further electrically connected by a microstrip line section. Such an arrangement leads to the emergence of a notched-band owing to the out-ofphase...
This paper summarizes recent researches on miniaturization of planar microwave passive components, in Computational Electromagnetics Laboratory at University of Electronic Science and Technology of China. Several filters and couplers are introduced, which can realize high performance with compact structures.
Terahertz pulsed imaging (TPItrade) is a non-ionizing and non-destructive technique. Image contrast has been seen between normal and diseased tissues in ex vivo measurements. Due to its coherent detection, TPI can easily reveal the dielectric properties of samples and recently it has been used for studying a wide range of biological materials. In this study, we try to differentiate between freshly...
We present a novel and compact six-mirror cavity configuration to combine four beams intracavity for energy scaling. A single beam output exceeding 453 mJ with 165 mus duration is obtained, with the combination efficiency of 90.7%.
The treatment of dormitory and refectory mixed wastewater by a submerged flat membrane bioreactor (MBR) was studied. The A/O MBR system treated wastewater 4 m3/d. The mean removal efficiency of BOD5 and CODCr was more than 95% with the influent concentration of 100~500 mg/L BOD5 and 120-900 mg/L CODCr. It was proved that active carbon treatment reduced effluent chroma effectively. At the steady working...
The methodology of delamination mapping is used to transform the requirement feature into the structure feature. After transforming, several schemes that meet the requirements can be gained. In the paper, Analytic Hierarchy Process (AHP) method is used in the manufacturability evaluation for part structure scheme without process planning. Through the manufacturability measurement, the best structure...
A slot-line electromagnetic energy coupler operating at 915 MHz for noninvasive diagnostic applications is described. The coupler is well matched when it is coupled to the biological tissue (VSWR < 1.5), its structure is simple and energy coupling efficiency is high.
