An improved type of elliptical jacket polarization maintaining fiber was developed by using a modified chemical vapor deposition method with special treatment.
Piezoelectric ceramics (Na0.5Bi0.5)0.92Ba0.08 TiO3 +x% MnCO3 (BNBT-Mn, x= 0 - 1. 6, mass fraction)were synthesized by conventional solid state reaction. The res
