Multiple reflections in an extended hemispherical lens are shown to exhibit distinctly different Gaussian characters. It is demonstrated that the second- and third-order bounces of the electromagnetic fields within the electrically large lens result in contributions with spot sizes and locations that are uncorrelated with the fundamental Gaussian-beam-like radiation from a small antenna located at the lens focus. We present the optical properties (Gaussicities and power levels at the beam waist) of such higher-order lens reflections. The impacts of these reflections on a typical quasi-optical spectroscopy setup are discussed. The relative received power densities are computed and compared with measurements for each higher-order reflection. The agreement between the measurement and theory indicates that the adopted method is a reliable and efficient tool for characterization of the dominant reflections from extended hemispherical lenses.
