permittivities

Permittivity is a measure of the ability of a material to store an electric field. It is a fundamental property in electromagnetism and is crucial in the design and analysis of electronic devices, antennas, and other electrical systems. Permittivity is typically denoted by the Greek letter epsilon (ε) and is expressed in farads per meter (F/m).

There are two types of permittivity: absolute permittivity (ε) and relative permittivity (εr). Absolute permittivity is the

Permittivity is influenced by several factors, including the material's composition, temperature, and frequency of the applied

In practice, permittivity is often measured using techniques such as capacitance measurements, resonant cavity methods, or
