paperback. Etat : Good. Our good condition books are generally good for reading but not for gifting or collecting. They could have imperfections such as creasing, fanning, inscriptions, margin notes, yellowing, staining on edge or cover or pages, bumps, scuffs, etc etc (sometimes multiple of these). It's a wide category that encompasses anything that isn't almost-new down to anything that is slightly better than poor. We would NOT recommend gifting Good books - these should be considered reading copies. Our books are dispatched from a Yorkshire former cotton mill. We list via barcode/ISBN so please note that the images are stock images and may not be the exact copy you receive, furthermore the details about edition and year might not be accurate as many publishers reuse the same ISBN for multiple editions and as we simply scan a barcode or enter an ISBN we do not check the validity of the edition data when listing. If you're looking for an exact edition please don't order (at least not without checking with us first, although we don't always have time to check). We aim to dispatch prompty, the service used will depend on order value and book size. We can ship to most countries, see our shipping policies. Payment is via Abe only. …

Hardback. Etat : New. Over the last twenty years Corrugated horns have become widely used as feeds for microwave reflector antennas because of their high efficiency, good pattern symmetry and low cross-polarisation. They are increasingly used in antennas for satellite communications, radar, microwave point to point communications and radio astronomy. The authors draw on more than fifteen years experience to write the first book to appear devoted to the theory and design of corrugated horns and scalar feeds. The book explains why hybrid mode feeds are ideal feeds for reflectors. The propagation and radiation behaviour of cylindrical corrugated waveguides, narrow flare angle conical corrugated horns and wide flare angle corrugated horns are described. Factors relevant to the practical design of corrugated horns are discussed. Other topics treated include the measurement of corrugated horns. …
