## Abstract In this letter, a sampled Bragg grating (SBG) with a chirp in the sampling period (CSP) is fabricated and experimentally investigated for the first time. Its spectrum response shows that the effective chirp in the grating period (CGP) varies among stopbands, which is consistent with the
## Abstract In this study, specimens of a high‐copper amalgam, prepared at different final Hg contents, were examined in several different experiments. The results showed that as the Hg content is increased, a point is reached beyond which creep and the amount of Sn in γ~1~ exhibit a sudden increas
