The 4th edition of this classic text provides a thorough coverage of RF and microwave engineering concepts, starting from fundamental principles of electrical engineering, with applications to microwave circuits and devices of practical importance. Coverage includes microwave network analysis, impedance matching, directional couplers and hybrids, microwave filters, ferrite devices, noise, nonlinear effects, and the design of microwave oscillators, amplifiers, and mixers [...]

Sight is the dominant sense of mankind to apprehend the world at the earth scale and beyond the frontiers of the infinite, from the nanometer to the incommensurable. Primarily based on sunlight and natural and artificial light sources, optics has been the major companion of spectroscopy since scientific observation began. [...]

Coherence and polarization are two of the intrinsic properties of a light field, which play a crucial role in determining the light beam propagation and light–matter interaction. The manipulation of coherence and polarization was recognized as an available method to produce many peculiar physical phenomena, which can be superior in some of these applications, such as free-space optical communications, microdensitometry, optical information processing, and plasmonics. [...]

This Reprint comprises all of the accepted articles published as part of the Special Issue “Mathematical Methods and Applications for Artificial Intelligence and Computer Vision”. The aim of this Special Issue was to publish recent theoretical and applied studies in computational intelligence and related fields, with a particular focus on computer vision [...]

Numerous significant ideas in applied mathematics have been formulated within the framework of ordinary or partial differential equations, which provides a language for the illustration of these ideas. Through the years, mathematicians and scientists have developed extensions of these methodologies across almost all areas of science and technology. [...]

This open access book gives a systematic introduction into the spectral theory of differential operators on metric graphs. Main focus is on the fundamental relations between the spectrum and the geometry of the underlying graph. [...]
