Radio Absorptive Properties of γ-Fe_2O_3 and T_iO_2 Composite Materials (Part 3)

Abstract

Radio absorptive properties in (γ-Fe_2O_3/T_iO_2)=(90/10) weight ratio composite materials for VHF, UHF and GHz band have been investigated. Permittivities and permeabilities Of (γ-Fe_2O_3/T_iO_2) composite materials are discussed for optimum trial design for radio absorptive sample that are indispensable for protection of electric equipment from external noise. The absorption properties of the sample with 0.2 cm in thickness demonstrates 681 MHz in bandwidth centered at 4.45 GHz as an experimental example.
