• . [3] on plasmon resonance Raman scattering. For the microwave irradiation, a standard domestic microwave oven would offer a simple practical source at νRF = 2.45 GHz, i.e., hνRF ≈ 1.01·10−2 meV. As this is much smaller than the above phonon-related values, the peak outcome of the THz radiation is not

• radius (r0)max ≈ 2.11·102 nm. A choice of radius of say r0 = 20 nm, would securely help against a “direct” heating. The suggested idea of transforming THz “sound” into THz electromagnetic waves can hopefully be realized as a source of continuous THz radiation. Figure 4 depicts a possible scheme. As a

• chamber, where the GNBs are exposed to both direct irradiation from the magnetron and to that reflected from the chamber walls. Effectively, the microwave photons could be absorbed anyway inside the GNBs, where consequently the THz photons will be emitted. The resulting THz radiation is channeled out of
