General Aspects of the Theory of Multielement Systems of Thin Impedance Vibrators and Narrow Slots , impedance, or partially impedance surface ., some parts of which can be removed to infinity. The volume . is coupling with another arbitrary volume . through holes . . cut in the common surface between the two volumes. The boundary wall between the coupling volumes . and . has an infinitely small thickness in the region of the coupling holes.

Ultrawideband Combined Vibrator-Slot Antenna Arrays,uch as IRA (Baum in Radiation of impulse-like transient fields, pp 1–29, 1989 ; Baum et al. in Proc IEEE 92:1096–1109, 2004 ; Miletic and Olcan in IEEE Trans Antennas Propag 70:6414–6422, 2022 ), and antenna arrays. For example, there are MIMO communication systems that need to develop ultra-wideband antenna arrays.

Excitation of Electromagnetic Fields in Electrodynamic Volumes with Coordinate Boundaries,This Chapter briefly presents basic equations, boundary conditions and tensor Green’s functions for studying electromagnetic fields, which will be used throughout the book. This chapter with comments on some aspects of electrodynamics theory, will allow a reader to read the book without searching for additional references.

Impedance Synthesis for Vibrator Antenna Arrays,In this Section a new method of impedance synthesis of antenna array radiation fields based on a single methodological conception is presented. At first, an approximate solution for the current in the thin vibrator with variable impedance was obtained using the partial averaging operation of the integral–differential equation.
