You mentioned in some other thread earlier that these kinds of structures require > 3D.
Also that the Maxwell-equations need to be extended to higher dimensions to achieve that.
How about starting the whole discussion from the extended equations…
If i understood correctly what FT said that the main problem is to get enough electromagnetic excitation power in the THz-range. Their solution is to create very sharp, high dU/dt (or dI/dt), pulses and wish enough harmonic components in the high…
But where was Ruby's nice hat in this interview ?
In addition to the results they have achieved there are two key-points here.
1) They can repeat the experiments by careful and well documented (also boring) test-design.
2) Collaboration between scientists. Montgomery Childs seems to be a…
