Query: On Two-cavity Coupling   This work presents research results on a novel analytical model of
electromagnetic systems coupling through small size holes. The key problem
regarding coupling of two cavities through an aperture in separating screen of
finite thickness without making assumption on smallness of any parameters is
considered. We are the first to calculate on the base of rigorous
electromagnetic approach the coupling coefficients of the cylindrical cavities
within the limit of small aperture and infinitely thin separating screen. The
numeric results of electromagnetic characteristic dependencies that have been
impossible to perform on the base of previous models are given.
