Enhanced dielectric performance of PVDF composites doped with MnO2@carbon particles
Journal of Science: Advanced Materials and Devices, 2023 Herein, a method is proposed for preparing MnO2@carbon core–shell particles and MnO2@carbon/polyvinylidene fluoride (PVDF) composite films. The effect of MnO2@carbon core–shell particles on the dielectric properties of polymer composites was investigated.

Circularly polarised dielectric resonator antenna
Electronics Letters, 1994 A circularly polarised dielectric resonator antenna is reported. The circular polarisation is obtained by exciting the two orthogonal HE/sub 11 delta / modes of a cylindrical ring dielectric resonator in phase-quadrature. Measured results show that the antenna has an axial ratio of less than 3 dB over a beam width of 100 degrees with a minimum value of
