Microwave-absorbing properties of Ni0.50–xZn0.50−xMe2xFe2O4 (Me=Cu, Mn, Mg) ferrite–wax composite in X-band frequencies

Synthesis and characterizations of spinel MnFe2O4 nanorod by seed–hydrothermal route

“…Spinel ferrites have received renewed interest in technologically anchored modern society due to their promising application in microwave adsorption [1,2], electrode materials [3], environmental remediation [4][5] and drug-loading materials [6]. The wide applications can be ascribed to their excellent magnetic properties and chemical stability [7].…”

Fabrication and microwave absorbing properties of Ni–Zn spinel ferrites

“…One of the frequently used methods to tune the complex permeability of spinel ferrites is to dope the ferrites with many metallic ions, such as Cu, Zn, Co, Li, Mn, Mg, etc. [33][34][35][36][37][38]. For this purpose, some attempts were made to verify the correlation between the material constants, permittivity (ε r = ε − jε ) and permeability ( r = − j ) and the microwave absorption in the sintered ferrites that contain divalent metal ions [1,[33][34][35][36][37][38][39][40][41][42][43][44].…”

A cost effective solution for development of broadband radar absorbing material using electronic waste

“…As per Eqs. (1) and (2), it can be observed that reflection loss strongly depend on complex permittivity and permeability values; therefore, primary variation of reflection loss Table 1 Comparison of dielectric and magnetic properties of an electronic waste with recently reported waste materials in X-band frequency range. with frequency may be considered to be the combined effect of dielectric and magnetic loss of materials.…”

“…According to generalized transmission line theory, the reflection loss values for a single layer absorber has been calculated from experimentally measured complex permittivity and permeability at given frequency and absorber layer thickness using the following equations [1]:…”

“…The X-band frequency radar systems are well known in defence sector for their high resolution imaging as well as greater precision target identification [1]. Since World War II, radar absorbing materials (RAMs) have received much attention of researchers due to their unique and promising applications in the field of modern stealth technology of aircrafts, warships, tanks and missiles by making them invisible to radar wave [2].…”
