Include Ahmed Nabih's data

[driftregion]

Ahmed Nabih (@asalahnabih) recently published an MIT licensed dataset containing permeability, permittivity, and loss data for a number of materials here: https://github.com/asalahnabih/magneto

Please consider including these data in materialdatabase.

Nice data set, also with a very good measurement method.

• up to very high frequencies, more than existing material data in our database
• very good for validation with other data in the database
• for 25 °C only

Currently we have no capability to include the data - but will keep in in our backlog for future. Thanks for informing us about this nice data set!
