Hemispherical antenna
Web6 apr. 2024 · The PCA detector is attached to a Si hemispherical lens with diameter of 50.8 mm, allowing us to collect more of the THz waves within the emission cone of the PCA emitter. However, the large diameter (more than 4× those of conventional lenses), also means that there is a significant path difference between the THz waves collected close … http://uuki.kapsi.fi/qha.html
