Evaluation of the influence of parasitic electromagnetic effects in the development of radio engineering and electronics products has always been an urgent problem. However, the sources and receptors of the electromagnetic field that interferes in microradioelectronic products are not only conductors, the influence of which was studied earlier, but also objects, the largest linear size of which is relatively small in comparison with the length of the film conductor.

Goal of the work is to create a methodology for assessing cross talk in microelectronic objects with a heterogeneous structure. The article presents a technique for computation of the crosstalk in a small-dimensions object-receptor. The technique is based upon a mathematical model of the electromagnetic field created by a rectangular film conductor in a flat-stratified medium. The model employs Green’s function for the wave equation; the mentioned Green’s function is obtained by means of the method of the equivalent propagation constant, which enabled to diminish the computational capacity of the model to a significant degree. The peculiarities of computation of the crosstalk voltage in a small-dimension object-receptor with a non-uniform structure are considered in contradistinction to a computation of the crosstalk voltage in a metal film conductor having a quasi-uniform structure, a transistor of a thinfilm integrated circuit being a representative instance. Analytical expression for the cross-talk voltage is obtained, techniques for its computation are suggested.

The methods and models proposed in this article can be used in the development of mathematical and CAD software for radio engineering and electronics products.
