Great progress has been made in developing and using numerical methods for solving electromagnetic field problems at low frequency recently. Many of these problems refer to eddy currents which appear in various electromagnetic devices.

Originally such problems were tackled by analytical solutions which are limited to simple geometries and linear materials. In practice though all electromagnetic devices have complex boundaries, include non-linear materials, and may be treated exclusively by numerical methods.

This book gives systematically the matehmatical simulation of existing methods and discusses the siscretization of relevant equations. The methods described are: finite difference, finite sums, finite element, boundary element, and some variants. Physical connotations of methods and problems are also given.

Recensione

a pleasure to welcome a new book on numerical modelling by one of the original Greek authors and a colleague from Poland ... There is in fact a gem of insight on almost every page ... Throughout the text the references are very helpful and, in summary, the authors are to be cogratulated in producing an excellent book. As usual the Clarendon Press have produced a text of high quality. (Richard Stoll, ICS Newsletter)

Descrizione libreria

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
