(c) Electromagnetic (EM) Fields These are often described generically as Radio Frequency (RF) fields as they are widely used for radio/radar emissions although the EM spectrum extends over a much wider range in practice, including IR, UV and the visible bands. An EM field is taken to comprise both E and H (Electric and Magnetic) components, which are separately detectable and measurable. Close to their origin (normally known as the source or transmitter) their relative amplitudes and phase are usually complex, but after a short distance the resultant wavefront becomes stable. In the UAP context the main interest is in whether a UAP body radiates EM waves, other than those in the visible part of the spectrum - which are present anyway, as the means by which a UAP is most often seen. The polarisation of an EM field is defined by the orientation of its E field to the horizon, but since an EM wavefront might be rotated, then both elliptical and circular emissions can occur.
Currently, the field characteristics of a UAP are unknown but it is a corroborated fact that, in addition to light (and sometimes heat), some sort of field is emanated which has adverse effects on some people when they are close to the source. A search was therefore made to identify possible effects on people exposed to all three of the main options (a) to (c) above, both physical and mental. The following information is included because of its applicability to the subject, to assist in future analysis and elimination, and especially because of the discoveries at Working Paper No. 25.
Annex D considers EM effects on Equipment and Objects and Annex F non-ionising effects on humans.
MAGNETIC FIELD EFFECTS
5. The findings due to purely magnetic effects are considered to be of prime importance in the UAP content because of the response of the human brain and the similarity to UAP reporting. This has warranted the separate Working Paper No. 25.
A first general effects summary chart for electromagnetic (microwave) effects on humans is at Table F-1.
