In plain terms

A 2013 review gives three references for the 1 kilowatt per square metre figure: two Japanese papers from 1995 and 1996, and a 1981 paper by Perkins and Goldman.

The claim as recorded

The three references a 2013 Proceedings of the IEEE review gives for its claim that ionospheric effects are not critical at around 1 kilowatt per square metre at 5.8 GHz are a 1995 Japanese numerical simulation paper, a 1996 Japanese numerical self-focusing paper, and Perkins and Goldman 1981.

Scope and limits

References 22 and 23 were NOT obtained. Both are closed Wiley content and four independent services confirm no open copy exists anywhere. So the substance of the 1 kilowatt per square metre claim is still unread and CLM-0112's tension with the 425 and 189 watts per square metre threshold estimates is unresolved.

What it assumes

No assumptions are recorded against this claim.

Where it comes from

SRC-127 Microwave Power Transmission Technologies for Solar Power Satellites, Proceedings of the IEEE...
page 1447, verified against a 300 dpi render of the reference-list page with no discrepancy against the text layer. Reference 22 is Matsumoto, Hashino, Yashiro, Shinohara and Ohmura 1995; reference 23 is Shinohara, Matsumoto and Shklyar 1996; reference 24 is Perkins and Goldman 1981.
