Abstract
Dispersion and loss properties of hollow core tube fibers with elliptical cross section are numerically investigated. Results show unusual characteristics. For example, the birefringence always goes to zero in the middle of the low loss region irrespectively of the ellipticity and it always assume opposite sign approaching the two edges of the low loss region.
