Ristelektrirežiim on elektromagnetlaine levimise olek, kus elektriväli on rangelt risti levimissuunaga. Kuigi elektriväljal puudub laine levimissuunas komponent, sisaldab aga magnetväli nii põik- kui ka pikikomponenti.
A transverse electric (TE) mode is an electromagnetic wave propagation state where the electric field is strictly perpendicular to the direction of propagation. While the electric field has no component in the direction of the wave's travel, the magnetic field contains both transverse and longitudinal components.
