The full-wave analysis of the scattering problem is based on the Mutter's boundary integral-equations (MB1E) that are uniquely solvable. A Calerkin discretization scheme with a trigonometric basis leads tu a very efficient numerical algorithm. The numerical results related to the focusability of the lens versus its rear-side extension and the angle of the plane-wave incidence, as well as near-field profiles, demonstrate strong resonances. Such effects can change the principles of optimal design of lens-based receivers.EnglishBoundary integral equationsDielectric lensFocusabilityAlgorithmsComputer simulationDielectric amplifiersElectromagnetic wavesError analysisFourier transformsGeometrical opticsGreen's functionIntegral equationsMathematical modelsArticle10.1002/mop.205201098-2760
