Abstract :
The successful application of finite difference time domain (FD-TD) methods to millimetric planar transmission lines presupposes a satisfactory answer to the problem of infinite line termination (absorbing boundary condition) in the presence of high frequency dispersion. A technique is proposed that reduces residual reflection to less than 1% for microstrip and coplanar line circuits up to and beyond 50 GHz. Four examples, two in microstrip, two in coplanar waveguide, are discussed
