Effects of High-Energy Ball Milling on the Microwave Absorption Properties of Sr0.9Nd0.1Fe12O19

“…Recent developments in microwave absorber technology have been focused on the materials with high wave absorption coefficient, good physical performance, and lower production cost [3,4]. There are a variety of absorber materials that can be used to suppress EMI depending on their suitability for low or high frequency applications [5][6][7]. According to the thickness and working frequency bandwidth, the magnetic composites have obvious advantages.…”

Microwave Dielectric Properties of (1 − x)(Mg0.95Ni0.05)TiO3–x(Ca0.8Sr0.2)TiO3 Ceramic System With Near‐Zero Temperature Coefficient

“…In particular, size reduction is mainly a result from the use of high dielectric constant material as the wavelength (λ) in dielectrics is inversely proportional to according to the relation where λ o is the wavelength in vacuum. However, as the frequency of interest is extended from ISM (industrial, scientific, and medical) bands to millimeter wave range, materials with high dielectric constant tend to become a less of interest . Consequently, high quality factor together with low dielectric constant would play a more prominent role instead, as high quality factor can significantly reduce the dielectric loss, and low dielectric constant allows a fast time for electronic signal transition at ultra high frequencies.…”

“…Zero τ f value (temperature coefficient of resonant frequency) is also one of the major requirements for dielectric materials to allow a frequency‐stable passive component. The most convenient and promising way to achieve a zero τ f value is to combine two compounds having negative and positive τ f values to form a solid solution or mixed phases . However, high dielectric constant materials, in general, exhibit high dielectric loss (low Q × f value) and large positive τ f value, whereas low loss ceramics are usually accompanied by low ε r value and negative τ f value .…”

Characterization and dielectric behavior of a new dielectric ceramics MgTiO3–Ca0.8Sr0.2TiO3 at microwave frequencies

“…Basically, a dielectric resonator is a ceramic compact with high dielectric constant (ε r > 25), low dielectric loss or high quality factor (Q > 2000) and good temperature stability (near-zero temperature coefficient of resonant frequency, f ) at microwave frequencies [2][3][4][5][6][7][8][9][10][11][12][13].…”
