A novel microstrip bandpass filter using stepped impedance resonators (SIRs) with asymmetric open stub-loaded is proposed in this paper. The filter uses asymmetric open stubs as capacitive loads, resulting in higher-order spurious frequencies suppres

The properties of ceramic materials are strongly dependent on their microstructure. Ceramic microscopic image processing may be divided into two main procedures: image preprocessing for noise reduction to clarify the image and image segmentation for

Raman scattering has been performed on a- Si:H /a- SiN x: H superlattices in this letter. We have observed the zone-folding effects on longitudinal acoustical phonons in a- Si:H /a- SiN x: H superlattices. The experimental results confirm the theoret
