The theory and method of measuring the electrostatic force and the permittivity of vacuum in parallel plate capacitor by electronic balance are introduced.
There is the permittivity vacuum. It is all up there.
This is the permittivity of vacuum.
The cold-pressing ceramic processing technique was used to prepare high-permittivity Barium Titanate ceramics.
The resonance and tunneling problem of pairing conjugate structure consisting of negative permittivity and negative permeability materials were studied by using transfer matrix methods.
Recently, a new type of artificial material which exhibits simultaneously negative effective permittivity and permeability over a certain frequency band has attracted a great attention.
