Abstract :
A finite element method based on the use of Whitney forms for the space discretization of the fields and a leap-frog scheme in time is presented. This method has both the flexibility related to a finite element mesh conforming to the geometry and the capability of time domain techniques to get overall frequency band responses with one calculation. The efficiency of the method is shown through two examples. The accuracy is checked with the case study of a rectangular cavity. A practical case of a via hole with a circular or square cross-section is also studied and compared to experimental data.
