Thin impedance vibrators

This monograph builds on the foundations of thin impedance vibrator antenna theory and extends the classical theory of thin, perfectly conducting vibrators. The impedance concept is widely regarded as one of the most versatile models for wave phenomena, applying across many practical problems in electrodynamics. Its adaptability also makes it possible to pursue further analytical solutions, which can simplify the mathematical setup of boundary value problems. The author aims to broaden where impedance vibrator antennas can be used within today's complex radio and electronic systems and devices.

The book covers general principles of impedance vibrator theory in the spatial-frequency domain. It then examines how these vibrators radiate electromagnetic waves in free space and in material media, including over a perfectly conducting plane. Further chapters address the scattering of waves by irregular impedance vibrators in free space and in a rectangular waveguide, along with a generalized method of induced electromotive forces for analysing vibrator characteristics. Radiation from radial impedance vibrators placed on a perfectly conducting sphere is also treated.

The authors' original research is presented for practicing engineers and designers of antenna and waveguide systems. Written in an academic style, the text also suits students and postgraduate researchers in radio engineering and radiophysics. Its concluding section outlines a number of applied problems that could serve as starting points for doctoral projects.
