Popis:	The dynamical behavior of a fluxon in a semi-annular long Josephson junction in the presence of an ac-drive is studied. The non-uniformity due to the non uniform distribution of bias current is investigated. The oscillating potential is found to increase the depinning current. Finite difference method is used for numerical analysis and the response of the system to the ac-bias is studied. The creation and annihilation of fluxon is also demonstrated numerically for the first, second and third Zero-Field step cases. Comment: 10 pages 8 figures
