Abstract-This paper presents a simple and alternative approach for the analysis of inductive waveguide microwave components. The technique uses a surface integral equation formulation, in which the contours of the waveguide walls and of the inner obstacles are all discretized using triangular basis functions. In order to avoid the relative convergence problem of other techniques based on mode matching, an alternative port treatment is used. The technique is based on the application of the extinction theorem using the spatial representation of the Green's functions in the terminal waveguides. In addition, the Fast Multipole Method is proposed in order to reduce the computational cost for large problems. Different complex structures are analyzed, including microwave bandpass filters with elliptic transfer functions, waveguide bends and T-junctions. Results show the high accuracy and versatility of the technique derived.

“…In the right y-axis of the same graphic we show the relation between the diagonal term M 22 , and the required resonant frequency of the resonator, according to equation (3). Using this right y-axis, we can compute the required resonant frequency corresponding to the diagonal term M 22 = 1.2866 (see labels 1 and 2 in Fig.…”

“…Other analytical techniques can also be used for specific coupling topologies, as for instance the one reported in [2]. An example of a second order bandpass transversal filter based on the use of simple inductive discontinuities in a rectangular cavity was introduced in [3]. Two bandpass transversal filters implemented in simple microstrip structures were also presented in [4].…”

A novel algorithm to design hybrid waveguide-microstrip transversal microwave filters is proposed in this paper. The idea consists in isolating each resonator involved in the filter structure, to synthesize individually its frequency response, both in resonant frequency and bandwidth. These separated optimizations lead to the dimensions of the filtering structure to meet the requirements of a certain, specified transfer function. The novel algorithm introduces an iterative procedure in order to synthesize the direct coupling term between source and load, which is always present in the hybrid filter structure. The whole algorithm is illustrated by means of a design example, where a very good agreement between the ideal specified transfer function and the final frequency response of the designed hybrid filter is obtained. A second different design example, which has been manufactured and tested, is also included for validation.

The objective of this article is to describe the formulation of multimode equivalent network representations of waveguide junctions. Both planar and arbitrary junctions are discussed, thereby covering essentially all possible cases of engineering interest for microwave and millimeter‐wave applications. The theory presented in this article effectively transforms complex field problems into linear algebraic problems of simple solution. The theory described is rigorous and computationally very efficient and can therefore be used as a very solid theoretical frame for the development of advanced full‐wave electromagnetic simulation computer programs. In addition to theory, a number of applications are also demonstrated showing very good agreement between measured and simulated performances, thereby fully validating the theory presented.
