This paper investigates and compares the via-coupling and gap-coupling mechanisms in end-coupled structures, in which the former is realized by the shared metallic via between two resonators. Comparisons show that the via-coupling provides more design flexibility, owns better tolerance to fabrication errors and requires more ordinary substrate than the traditional gap-coupling. These merits have been...
As a novel packaging material, glass has good light transmission and insulation, getting people's attention. In the paper, ANSYS software was used to simulate heat dissipation performance of the chip-on-board for LED chips packaging on glass substrate, analyze effects of the substrate material, substrate thickness, chip gaps, chip sizes and convection conditions on COB heat dissipation performance...

In this paper, we demonstrate a novel flexible gas sensor based on polypyrrole (PPy) coated SnO2 nanoparticles that can be employed to detect low concentrations of NO2 (0.5 – 5 ppm) at room temperature. This low-cost, easy-fabrication and wearable gas sensor was fabricated on PET substrate. The sensitive film was formed by first drop casting the solution of SnO2 nanoparticles and FeCl3 on the as patterned...
This paper presented a novel method to realize millimeter wave integrated antenna and waveguide. The antenna has bandwidth great than 90 GHz and its measured gain is about 10.8 dB Pattern of the antenna has been measured and agree with the simulated results.
A silicon based THz substrate integrated waveguide (SIW) bandpass filter with a pair of antipodal linearly tapered slot Antennas (ALTSA) is designed and fabricated with MEMS process. A prototype with passband range 350GHz~370GHz is measured by using a quasi-optic measurement system. The measured data are in agreement with the simulated results, which show the filter has good selection performance...
Paphia undulate was used to prepare low-molecular peptides by enzyme autolysis. The optimum condition for autolysis was studied to reach a maximum yield of peptides. Results showed that the yield of low-molecular peptides was 4.33% and 78.57% of the total protein can be recovered under the optimized condition: pH 6.5, temperature 45 Degrees Celsius, reaction time 4h, ratio of starting material and...
For low microwave band, the size of substrate integrated waveguide (SIW) couplers still need to be further reduced though other advantages of low profile, low insertion loss, low cost etc. are very remarkable. In this letter, novel substrate integrated folded waveguide (SIFW) narrow-wall single-slot and double-slot directional couplers are designed and implemented. The measured results are in good...
