Abstract
Model problems in the theory of ultra-wide-band horn-type antennas are initial boundary value problems in infinite domains with locally inhomogeneous and perfectly conducting compact scattering objects. The key to their efficient solution lies in the correct truncation of a computational domain, which on the one hand, reduces the fundamentally open problem to the closed one, and on the other hand, has little or no effect on the accuracy and reliability of resulting numerical data
