relative permittivity

Relative Permittivity of PCB Substrates: High

2019/9/5Relative permittivity can vary widely from ~2 to above ~10 over a range of frequencies. The same applies to the imaginary part of the relative permittivity. If you look at data on these quantities in a variety of materials, you'll find that most manufacturers only quote a value at specific frequencies, or they don't even specify a frequency.

Effective Permittivity of Biological Tissue: Comparison of

Relative permittivity of tissue is the ratio of permittivity of tissue and the permittivity of vacuum (); that is, When blood is concerned, it can be easily shaped for detecting the capacitance. But elastic properties of other tissues may be influenced by attached proteins on biological membranes [ 18 ], and the detecting capacitance may be affected by the detection voltage of the measuring
