Abstract

We demonstrate irregular scattering structure frequency-dependent field control at terahertz frequencies by means of a TM10 to TM30 mode converter designed for operation near 300GHz and fabricated out of lithium niobate. Imaging of the electric fields in the sample, with a Fourier analysis of the time domain signal, yielded the performance as a function of frequency.
