Relative permittivity less than 1

WebJun 10, 2024 · Can relative permittivity be less than 1? For a static (electrostatic) electrical field is it ever possible (and for what material) that ε < 1? For the electric component of EMF field - when is it possible that ε < 1? WebJun 4, 2024 · So you can understand the permettivity as following, high permittivity materials permit or allow the forward electrical field to pass through more. Regarding the second part, Metals have almost infinite permittivity. According to my knowledge the real relative permittivity of materials is almost 1 (not infinity).
