| Abstract: | In this paper,the preparation of BaMnZn-W type hexagonal plane crystal micro-absorbing materials and their absorption properties have been studied and analysized by substituting Fe 3+ ions with Co 2+ and Ti 4+ ions. It is found that when the coat thickness is 1.06mm, three absorption peaks appear in the range of 7-10GHz frequencies. The absorption maximum is above 34dB. With increasing the content of Co 2+ and Ti 4+ ions. in the materials prepared with the same technique the frequency and coat thickness dependence of absorption properties has also been compared. |
