Fig. 3: Electromagnetic parameters and microstructure of S-MB ceramic composites.

a−d The real and imaginary parts of permittivity and loss tangent (tan δε) of S-MB ceramic composites. e, f Cole-Cole curves of S-MB ceramic composites. g, h Conduction loss and polarization loss in S-MB ceramic composites. i Polarization relaxation time τ of S-MB samples. j High-resolution TEM micrograph of sample S-MB-A, along with enlarged views of the corresponding regions 1-6 and their indexed FFT patterns. The yellow dashed lines highlight the heterointerfaces formed between the PDC-SiOC and the multi-borides.
