Sommario/riassunto

Focuses for the first time on materials development and applications of current research and theory for the main areas of applied linguistics (e.g. second language acquisition, pragmatics, vocabulary studies). There are many books on applied linguistic theory and research and there are now a number of books on the principled development of materials for language learning, but this book takes a new approach by connecting the two concerns. Each of its chapters first of all presents relevant theories and research conclusions for its area and then considers practical applications for materials development. The chapters achieve these applications by reporting and commenting on current theory and research, by analysing the match between current published materials and current theory and by suggesting and exemplifying applications of current theory to materials development. This will be an essential resource both for those studying or teaching materials development and for those studying or teaching applied linguistics.

Sommario/riassunto

The book explores electromagnetic (EM) waves, which are present everywhere—from radio, television, and cell phones to satellite dishes, antennas, and WiFi. The propagation of EM waves is governed by Maxwell's equations. When these waves pass through a medium, they slow down and refract, while in a metallic medium, they are reflected. Metallic boxes and pipes can store and direct EM waves, known as cavities and waveguides. Oscillating currents generate and transmit EM waves through antennas, allowing for long-distance communication after the waves propagate. Since oscillating currents emit EM waves, the author uses coaxial cables and transmission lines to reduce radiation and carry high-frequency currents efficiently. EM waves at very high frequencies in the optical range are responsible for transmitting visual information. The author also discusses lenses and optical instruments like telescopes and microscopes, which are used to magnify optical



signals. Additionally, the quantum mechanical origins of a material’s permittivity, which affects the speed of light through the medium, are examined.
