Abstract
The microwave absorption studies of hexaferrite composites prepared with [C
a(CoTi)(x)Fe12-2xO19](96.0)[La2O3](4.0) (x varying from 0.0 to 1.0 in steps
of 0.2) were made in the frequency rang from 8.0 to 12.4 GHz. The reflecti
on loss has been studied as a function of frequency, composition and thickn
ess of coating. The relationship of reflection loss with complex permeabili
ty (mu' - j mu ") and dielectric constant (epsilon' - j epsilon ") of compo
sites have been investigated in the X-band of microwave frequencies. The th
eoretically determined matching frequency has been compared with an experim
entally measured value at minimum reflection loss. The multifrequency measu
rements of mu* and epsilon* were made by the reflection/transmission techni
que. (C) 1999 Elsevier Science S.A. All rights reserved.
