• Finite-difference time-domain (FDTD)
• hybrid implicit-explicit (HIE)
• microstrip
• uniaxial perfectly matched layer (UPML)

This letter proposes a novel hybrid implicit-explicit finite-difference time-domain method with collocation in the direction of implicitization. In this direction, the method features increased accuracy, the reason being twofold: 1) the applied combination of interpolations and differentiations preserves second-order accuracy upon nonuniform discretization and 2) material boundaries are more accurately approximated by the grid. The method's stability and accuracy are verified by a microstrip line example. An appropriate PML is included.
