In this paper

according to the theory of microwave network and the concept of mesh wave impedance

the wave reflection of non-uniform mesh for FDTD technique is analyzed

and the concept of analysis and synthesis of mesh network is presented.The reflecting characteristic of mesh network is analyzed first.Then the procedure of synthesising a mesh network is deduced.On the basis of the above theory

network characteristics of non-uniform mesh

which can be used to match non-uniform mesh or improve the transmitted characteristic for a mesh wave to travel along the non-uniform mesh etc.

are realized in 1-D (TEM wave)

3-D microstrip structures and waveguide.
