MICROWAVE ABSORPTION CHARACTERISTICS OF SUBSTITUTED BA-(0.5)SR_(0.5)MXFE_((12-2X))O_(19) (M = CO~(2+)-ZR~(4+) AND CO~(2+)-TI~(4+)) SINTERED FERRITE AT X-BAND

摘要

The microwave reflection loss (RL) of four series of synthesized ferrites, Ba_(0.5)Sr_(0.5)Co_xZr_xFe_((12 - 2x))O_(19) and Ba_(0.5)Sr_(0.5)Co_xTi_xFe(12 - 2x)O_(19), have been measured using network analyzer in the frequency range from 8.2 to 12.4 GHz. The comprehensive analysis of RL is carried out as a function of substitution, frequency, and thickness. The various models contributing to large RL are described. The composition accompanying maximum microwave absorption is suggested.
