He must have been well cooked after all those years.

Here is a link to millimeter wave work at frequencies as high as60 GHz done
by Bose at President College in India in 1895!
https://www.cv.nrao.edu/~demerson/bose/bose.html
He used a spark gap connected to resonant metallic spheres as a source, and
metal to metal contacts using the surface oxide layer as a semiconductor for
detection for the receiver. With this home built equipment and other
components, polarizors, attenuators waveguides and the like he measured the
dielectric constants at millimeterwave frequencies of a number of dielectric
materials.
This will make a great science fair project when my kids get older.
Ok Ok Bose started his work in 1895, actual millimeter wave measurements
might have been as late as 1900.

I think this all traces back to James Clerk Maxwell.
