In the following table https://em.geosci.xyz/content/maxwell1_fundamentals/harmonic_planewaves_homogeneous/skindepth.html#skin-depth-for-various-materials the conductivity of air is given as 0 S/m, which results in an infinite skin depth, suggesting that an EM signal travels the whole globe...

courtesy of @prisae! prisae 11:49 PM The link given under "resources"=>"apps" on https://disc2017.geosci.xyz seems to be dead (https://notebooks.azure.com/lheagy/projects/em_apps). Are those notebooks stored somewhere else?

The equation for the wavelength of a plane wave in the frequency domain on this webpage (https://em.geosci.xyz/content/maxwell1_fundamentals/harmonic_planewaves_homogeneous/wavelength.html#harmonic-planewaves-homogeneous-wavelength-formula) does not seem right. The wavelength is defined by 2X \pi/wavenumber, where wavenumber,...

We should include a description for how people should cite EM geosci. I suggest we do something similar to [astropy](https://www.astropy.org/acknowledging.html) which starts the citation with "Astropy collaboration" and then lists...

Currently, authors must added to the contributors page and referenced within case_histories.json. As a result, manual entries cannot be included in the case_histories.json file. Hopefully something can be done about...

In the upgrade to the most recent sphinx in #546, I found that there are a whole suite of references that are not currently being cited in em geosci. This...

In order to upgrade to the latest version of the sphinx (closing issue #428), I removed the use of the equation bank in pr #546. The issue was that sphinx...

Hi, Seogi and Lindsey, I was checking this webpage https://simpegem1d.readthedocs.io/en/latest/api_EM1D.html, and noticed that the forward modeling (for both frequency domain and time domain EM) part is unfinished. I am interested...
