It is our great pleasure to announce the Nineteenth COMPUMAG Conference on the Computation of Electromagnetic Fields held between 30 June - 4 July, 2013 in Budapest, Hungary. Since it was organised in the first time in 1976 in Oxford, COMPUMAG has always been one of the most important gathering of researchers in the field of computational electromagnetics. The conference is aiming to provide a worldwide forum for engineers and physicists engaged in the theory and application of the numerical computation of electromagnetic fields. Thanks to the enthusiasm and efforts of those researchers, the computational electromagnetics is playing a more and more important role in the design optimisation of novel electromagnetic devices and systems. On behalf of the organising committee and the editorial board, we cordially invite you to come to Budapest in 2013 to attend the COMPUMAG 2013 conference.
