Zn2+-Enhanced Lithium Magnesium Molybdate Ultralow Temperature Cofired Ceramics for Terahertz Wavefront Modulation Applications

“…Apparently, the main reason for the shift of the diffraction peak (122) toward the lower diffraction angle is that the ionic radius of Zn 2+ (0.74 Å) is slightly larger than that of Mg 2+ (0.72 Å) . All XRD data are refined by Fullprof software. , The fitting results of LMZMO ( x = 0.06) ceramic refinement is shown in Figure c. In particular, the reasonable values (<10%) of R p , R wp , and R exp prove the reliability of the refinement results.…”

(Ni1/3Nb2/3)4+-Improved High-K Ba3Ti4Nb4O21 Microwave Dielectric Ceramics for Miniaturized All-Ceramic Radomes with 5G Beam-Splitting Function

“…Microwave dielectric ceramics are widely used as materials with excellent dielectric properties in the design of RF front-end passive devices, such as antennas, radomes, resonators, polarization converters, signal boosters, and filters. − With the rapid development of 5G communication technologies, researchers are increasingly aware of the importance of component miniaturization . Microwave dielectric ceramics with high dielectric constants have a unique advantage in terms of radome size.…”

Modulation of the Microwave Dielectric Properties of Si-Based Olivine Structured Ceramics Through the Variation of A-Site Ions

“…[1][2][3][4][5][6] This is due to their unique electrical and thermal properties, such as low and stable dielectric constant (ε r ), high quality factor (Q×f), and good insulation properties. [7][8][9][10] These characteristics lead to low signal losses and small phase shift errors in highfrequency microwave transmission, improving the quality of communication and the transmission rate. The excellent insulation performance of these ceramics also prevents the influence of electromagnetic interference on the circuit, ensuring the stability and reliability of the circuit.…”

“…Moreover, good thermal performance allows the ceramics to stably operate in high-temperature environments. [8][9][10][11][12][13][14][15][16][17][18] Microwave dielectric ceramics with an olivine structure and the general formula A 2 BO 4 (A = Mg, Zn, Ca, Ba; B = Si, Ge) have attracted much interest due to their thermal, mechanical, pyroelectric, and dielectric properties. There are two main types, Si-based and Ge-based olivine structured ceramics, with the space group Pbmn.…”
