Microwave absorption of NdFe magnetic powders tuned with impedance matching

Structural design and preparation of Ti3C2TxMXene/polymer composites for absorption-dominated electromagnetic interference shielding

“… 154 Jiang et al 155 demonstrated a Fe 3 O 4 -functionalized graphene nanoplate composite with good absorption of X-band EMWs due to its high impedance matching. Wang et al 156 also confirmed this result.…”

A coral-like nano-PCF composite as a broad-bandwidth microwave absorber

“…23,24 A good impedance matching ability of an absorber means most radiating microwaves penetrate the MWA. 25,26 Significant reflection loss will attenuate the incident microwaves, and the absorption strength may be extended. 27,28 We inspected the impedance match and reflection loss of PCF-3, PCF-4, PCF-5, and PCF-6 via the electromagnetic Fig.…”

Microwave Absorption Characteristic of ZnNd_(x)Fe_(2-x)O₄ System

“…The whole interaction of electromagnetic wave absorption is represented by the existence of impedance matching between the material (Zin)and the electromagnetic wave (Z0), while the impedance is influenced by the permeability and permittivity of the material. An impedance matching condition occurs if Zin = Z0 and presents a perfect absorption [5]. According to research reported by Teber [6] that zinc ferrite synthesized by the solgel method did not show the peak of microwave absorption.…”
