Abstract
AbstractIn this article, a Laguerre‐based discontinuous Galerkin time‐domain (DGTD) method using a new temporal basis function has been developed to solve transient electromagnetic problems. The new temporal basis function is a linear combination of weighted Laguerre polynomials, and can be easily implemented by adding some extra terms in the conventional Laguerre‐based DGTD method. With the proposed temporal basis function, initial condition of a general electromagnetic problem can be implicitly satisfied, and thus the resultant computational accuracy can be improved. Numerical results including a parallel‐plate waveguide, a dual‐mode circular waveguide filter, and a conducting ship demonstrate good performance of the proposed method.
