Quasi-Helmholtz Calder\'on Multiplicative Preconditioning for Higher-Order Global Multi-Trace Integral Equations
The paper presents a higher-order global multi-trace integral equation for time-harmonic electromagnetic scattering by composite objects. The higher-order multi-trace formulation is preconditioned with a Calder\'on multiplicative preconditioner using higher-order quasi-Helmholtz projectors. The higher-order quasi-Helmh...
