The multi‐dimensional asymptotic waveform evaluation (MD‐AWE) method is proposed as an extension of the conventional one dimensional asymptotic waveform evaluation (1D‐AWE) method. It can be applied in parameter analysis of structures, particularly with multiple variables, at which repeated calculations are required. The MD‐AWE is proposed at first, and then an adaptive hopping technique similar to the complex frequency hopping (CFH) technique to expand the approximation region of MD‐AWE is delivered, and this technique also helps to reduce the memory usage by taking lower order of MD‐AWE. In the end, two examples are given with good results, which show the efficiency and accuracy of the proposed method. © 2008 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2008.
