For comparison, we obtain an exact full-wave solution of a two-dimensional lens problem and use it as a benchmark for testing and validation of asymptotic models being considered.EnglishBenchmarkingDirectional patterns (antenna)LensesModelsOptical instrumentsAccurate modelingAsymptotic modelsDielectric lensQuasi-optical systemsSub millimetersTwo-dimensionalWave solutionsPhysical opticsArticle10.1364/JOSAA.26.000305
