    Different systems of units are often used in electrical engineering and in physics, causing difficulties when the need arises to convert from one system of units to another. This can be a problem in certain areas of electromagnetism, as in microwave engineering when dealing with magnetic materials and devices, or with electromagnetic-wave propagation. It arises, for example, when converting betwee... View full abstract»

Aims & Scope

The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design..
