Dielectric constant: The dielectric constant is defined as the relative permittivity for a substance or material. Although these terms may be seen to be related, it is often important to use the correct terms in the required place.
Dielectric Constant (Permitivity) In Electromagnetism, permittivity is one of the fundamental material parameters, which affects the propagation of Electric Fields. Permittivity is typically denoted by the syol ε.Absolute permittivity is the measure of the resistance
Depending where I look, I see values for the dielectric constant of alumina ranging from 9.4 (the HFSS material database) to 9.9 (given by my vendor but specified at 10 MHz). I''d like to get a good value for the dielectric constant to use for simulations from 10 to 50 GHz.
