- Amplifier's output meets has the filter, but outside effective stop band overtone and unwanted emission component.
- When some defects are introduced into the periodic photonic crystal,a number of defect modes appear in the stop band.
- The relationship between the stop band of colloidal crystals and the diameters of polymer microspheres were investigated by using UV Vis spectra.
利用紫外 -可见光谱研究了胶体晶的光禁带峰位与组成其微球粒径之间的关系 .
- Then, we fabricate different stack design of Distributed Bragg Reflector (DBR) on the different substrate and compare the difference of reflectivity and the diversity of stop band width.
- Put a band round the filing card to stop them falling on the floor.
- He left when the band began to beat out pop music.
