As shown in this paper, the first is responsible, for instance, for enhanced reflection from an isosceles 90° prism, if illuminated from the base. The second is responsible for the peaks in the total scattering and absorption cross-sections (ACSs) at the natural-mode frequencies. The numerical analysis is performed by solving the well-conditioned Muller-type boundary integral equation (IE) discretized using an algorithm with controlled accuracy.EnglishDielectric prismMuller integral equation (IE)Radar cross-section (RCS)Boundary integral equationsCylinders (shapes)Dielectric devicesGeometrical opticsIntegral equationsPrismsResonanceScatteringDielectric cylinderDielectric prismsElectromagnetic behaviorEnhanced reflectionsNatural resonanceTotal scatteringTriangular cross-sectionsRadar cross sectionArticle10.1109/TAP.2015.2404338
