Abstract :
A novel 2.5-D unconditionally stable finite-difference time-domain (US-FDTD) approach based on the Crank-Nicolson (CN) scheme has been introduced. Two of the three original multi-dimensional implicit equations of the CN scheme were reduced to tri-diagonal implicit ones, which significantly reduces the expensive CPU time for solving multi-dimensional implicit equations. Numerical examples for a hollow rectangular waveguide was included to illustrate the unconditional stability and efficiency of the proposed 2.5-D US-FDTD
