PEEK
Polyetheretherketone, thermoplastic material
Permeability
Amplification factor of the magnetic flux through the core material
Photolithography
Photolithography is a microsystems technology process in which photosensitive materials are structured by means of masking. This allows very small structures down to the nanometre range to be created.
Pores
Pores are microscopic gas inclusions that are formed by various mechanisms during casting or forging. Examples are stirred-in oxygen or pores as a result of shrinkage.
