Arbitrarily-shaped coupling windows in a rectangular waveguide are analyzed by using the method of moments and formulation for calculating their scattering parameters and equivalentcircuit parameters is presented in this paper.

Since no restriction is made on the shape of coupling windows in the analysis, the theoretical formulation and corresponding computer software obtained are applicable not only for analysis of various inductive or capacitive windows but also for analysis of arbitrarily-shaped windows in a rectangular waveguide as well.

A number of waveguide coupling windows are analyzed by using the present method and the satisfactory results are achieved by comparisons with ones given in some published literatures.

The three dimensional microstructure LAPS array chip based on the MEMS technology was introduced in detail. The surface of LAPS chip was of 5×7 sensitive elements, and on each of them were the silicon tips of 40×40 array, the array of optical coupling windows were setup on corresponding backside of the chip.

The width of coupling windows between the cavities and diameters of input output lines are acquired by modal frequency analysis and full wave optimization with commercial 3D full wave simulation software.

Directional patterns are constructed for different positions of the coupling windows and different directions of wave incidence.

A circuit model for coaxial cavity filter constructed from negative sub networks is presented in this paper. Based on this model, circuit parameters such as cavity coupling factors and input output locations of are optimized by commercial microwave circuit simulation software. The width of coupling windows between the cavities and diameters of input output lines are acquired by modal frequency analysis and full wave optimization with commercial 3D full wave simulation software. A six cavity band pass filter with a pass band of 100MHz at 2.4GHz designed in this way has the response coincided with the result of circuit simulation.
