Abstract An efficient iterative method is presented for fast analysis of cylindrically conformal microstrip
structure. Based on the transmission line modeling (TLM) method and the fast mode transform (FMT) theory, this
method accelerates the process of the calculation by introducing the concept of the transverse ic
waves instead of the transverse fields considered in the traditional algorithm. In the cylindrically stratified media,
the transverse ic waves are represented by mixed modal basis functions. Ultimately, the material form
of the modal admittance and the spectral reflection operator are deduced. The surface e
