Abstract

In this paper, the barium hexaferrite was successfully prepared by a conventional ceramic method and the precursors of BaCO3 and natural iron sand from Puger Beach, Jawa Timur-Indonesia. In order to develop a microwave absorbing material, the complex permeability, permittivity, and microwave absorption ability were investigated using a vector network analyzer (VNA) system Keysight PNA-L N5232A in the frequency range of 8.2 - 12.4 GHz. The results showed that the reflection loss values calculated from measured complex permeability and permittivity and exhibits optimum microwave absorption ability of barium hexaferrite.

Keywords: Barium ferrite, natural iron sand, reflection loss, microwave absorption ability
