Abstract The transmission factor of a corner in a dielectric-rod or optical-fiber waveguide is calculated applying the field matching method. The calculation is carried out with the exact field components of the HE11-mode in order to include also the cases of a glass fiber with a large index difference or a microwave dielectric-rod transmission line. The general expressions are subsequently simplified for weakly guided waves in the microwave or optical region. Very simple approximate formulas are derived for corners of small angle. The insertion loss of corners has been measured in the microwave region and has been found to agree with theory for angles not exceeding 40°. The electromagnetic field near corners has been recorded to give an insight in the transmission and radiation properties of corners.
