Electromagnetic Modelling

Electromagnetic Modelling may be used as an alternative or complementary approach to practical electromagnetic (EM) measurements, in cases where simplifications and realistic assumptions can be made. York EMC Services uses a wide range of computational modelling tools ranging from ‘Matlab’ to full wave solvers based on techniques such as the Transmission Line Matrix (TLM) method. Our experience of using these tools means cost effective methods can be readily identified and employed to meet specific requirements e.g. whether to use time or frequency domain techniques. Powerful computational tools can greatly assist in analysing and presenting large amounts of data that can result from measurement programmes such as EM mapping. York EMC Services has pioneered the use of Intermediate Level Circuit Modelling (ILCM) as a computational technique for rapid solution of EM problems. Where applicable, the technique offers solutions 3 to 4 orders of magnitude faster than other full wave solver computational techniques; making the difference between having a solution in seconds or days.
