Can someone provide resources on human electromagnetic frequencies?
For a start, you could learn about Bioelectromagnetics which is the study of the interaction between electromagnetic fields and biological entities (reference). Electro-magnetic fields are generated by the heart, brain, tissues and cells. These fields are in-turn affected by temperature and the overall mood of a person (reference).

There is a lot of research that is being conducted in the field. You can find a lot of papers relating to the field with a simple search on Google Scholar.

Well technically electromagnetic fields. 

There are instruments to measure EMF which are detailed in the Wikipedia page. Here is an article on an instrument made to measure the electromagnetic field of the heart (reference). 

Generally, if you have measured the electromagnetic fields in different parts of the body (eg: this article states that the electric field of the heart is up to 50 mV/m, and that of the brain and other vital organs up to 5 mV/m) then it shouldn't be too hard to generate them seeing that EMF generated is a low value (reference).
