Structure and electrical characteristics of poly(vinylidene …
A large permittivity of 610 together with a low loss tangent of 1.0 was achieved in the PVDF/SiC 50 wt% system. The composites exhibit dielectric relaxation process in the tested frequency range and such relaxation can be well described by the Cole-Cole equation.
Coined with the low loss requirements for multiple GHz RF signals in the package, there is a critical need for dielectrics with loss tangent ~0.001 and dielectric constant close to 2.0. Thin films of 5 to 10 µm are needed to achieve high-density routing with 3- to 5-µm …

Microwave Characterization of Silicon Carbide Sample at …
This article presents a microwave characterization at the ISM band (2.45 GHz) for the dielectric properties of a Silicon Carbide sample with high loss tangent from 25 C to 165 C. Different techniques were used to characterize the SiC sample: the cylindrical resonant cavity technique in transmission and reflection mode, the microstrip ring resonator and finally the near field microwave microscopy.

However, with some loss of material, the boule can be cut to a specific orientation, normally to within +/- 2 degrees. Sapphire that is cut with the C-axis perpendicular to the faces is generally referred to as being of `zero degree orientation` and the faces are considered to be in the c-plane (0001).
Silicon Carbide 102 micron (120 grit) Silicon Carbide is a hard, sharp, angular material primarily used for rough grinding. Under pressure, it fractures into smaller angular particles, and hence is an aggressive abrasive that removes a lot of glass quickly. Silicon carbide

A new composite ceramic material based on silicon carbide and complex oxide is synthesized by the microwave radiation method at a frequency of 2450 MHz. The material is characterized by loss tangent tan δ = 0.072 – 0.075 and has prospective appliions in radio and microwave technology. The material, owing to its radio-absorbing properties, can be used to fabrie heaters for microwave
Dielectric loss - Wikipedia
Dielectric loss quantifies a dielectric material''s inherent dissipation of electromagnetic energy (e.g. heat). It can be parameterized in terms of either the loss angle δ or the corresponding loss tangent tan δ.Both refer to the phasor in the complex plane whose real and imaginary parts are the resistive (lossy) component of an electromagnetic field and its reactive (lossless) counterpart.
