Several new advances in finite-difference computational electromagnetics will be presented: the ability to solve for cavity modes (frequency domain) in parallel with good scaling, the ability to include curved, embedded boundary dielectrics with second-order error, and the ability to obtain accurate surface fields for curved, embedded boundaries. The derivations of these algorithms and numerical results will be presented. A practical application is the development of a hybrid dielectric-metallic cavity that has high Q and low wakefields. The geometry of this cavity and its wake fields will be shown. Coffee / tea will be served after the seminar ATS Seminars Organisers: H. Burkhardt (BE) T. Stora (EN), G. De Rijk (TE)
