In this contribution, an enhanced 3-D differential surface admittance operator is proposed, facilitating accurate modeling of piecewise homogeneous cuboidal objects. By exploiting the analytical properties of entire-domain basis functions, material interfaces are effectively eliminated from the formulation, leading to a reduction in the number of unknowns without compromising the accuracy of the operator. After a validation of the novel approach, its effectiveness is demonstrated through the analysis of the impedance responses of on-chip interdigital capacitor structures.
An FDTD-TDDFT method for the EM/QM co-simulation of nanowire systems in the Lorenz gauge
Real-time time-dependent density functional theory (TDDFT) constitutes a cornerstone in the modeling of nanoscale materials. Although numerous application areas have already benefited from the technique,
