Resumen

Se presenta la solución exacta de Sommerfeld para el problema canónico bidimensional de difracción por una cuña con superficies perfectamente conductoras. A partir del planteamiento integral del problema, se presenta la solución de Malyuzhinets y se extiende el resultado para el caso de impedancia en las caras. Se desarrolla la solución asintótica de Keller para el problema y, a partir de la formulación integral de la solución exacta, se introducen los métodos generales para desarrollar soluciones asintóticas útiles desde el punto de vista computacional. Se utiliza una herramienta de simulación para comparar los resultados de computo numérico de la solución exacta y de una de las soluciones asintóticas del problema canónico. Se encuentra buen acuerdo y se verifica la dependencia de la precisión con la frecuencia para los métodos asintóticos.
