Recently, the challenges of the utilization of higher frequency bands for cellular systems have been attracting attention. In these high frequency bands, besides the higher propagation losses, the propagation channel tends to suffer more severe shadowing by pedestrians in the environments. In this paper, we carried out measurements in the 26GHz band in an indoor quasi-static environment for figuring...
This paper presents our recent progress for the development of low-AC loss Bi2223 tapes with interfilamentary oxide barriers. For the compatibility with Bi2223 phase formation during sintering, SrZrO3 was selected as barrier materials. Moreover, small amount of Bi2212 was mixed with SrZrO3 to improve its ductility for cold working. Although some breakages of barrier layers still existed, the effective...
