About This Special Issue
(1). Academic and industry background, and purpose of the special issue
Along with the voltage and capacity of the power transmission and transformation equipment rose to the highest level in the world, the modeling and prediction of the magnetic losses inside magnetic components under extreme excitation in large electromagnetic devices, are increasingly of interest, comparing with low voltage and capacity of equipment.
Most of the material property data used in industry application are usually measured at the specified standard conditions, which are considerably different from that obtained under the practical working conditions. However all the accurate and effective analysis need such working property data’s support. Therefore, the combination of advanced material property modeling and efficient industrial application is really important.

(2). Numerical modeling and magnetic property measurement
The numerical modeling and simulation of the magnetic losses in large electromagnetic device is quite challenging due to complicated 3-D structure with multi-scale, multi-material and multi-physics coupling. The electromagnetic properties of both the material and the components have to be measured under various working conditions, even some extreme excitations.
This part of the special issue focuses on electromagnetic property measurements and efficient numerical modeling under various conditions based on the upgraded benchmark models and industry-level models, recently done by the authors.

(3). Engineering-oriented validation based on benchmark and industry models
In order to validate the numerical modeling, a series of benchmark problems have been established by the international Compumag Society and widely applied in the computational electromagnetics community. Problem 21, as an engineering-oriented loss model was proposed by the authors, and the Problem 21-based benchmarking activities have been extended continuously for many years.
This part of the special issue is to emphasize that the benchmarking activities should be further enhanced for the modeling and simulation under extreme excitations, encountered in today’s large electromagnetic devices in electrical engineering, and present the recent research works done by the authors.
Note that (2) and (3) will contain articles to be submitted.
