✦ Synopsis

surface is smaller than that of the flat surface. That is because the Brewster angle between ground and snow is 50°. The 50°angle in snow corresponds to 35°in air by Snell's law. However, at the higher frequency of 36.5 GHz in Figure 4, volume scattering becomes important and obscures the Brewster-angle effect of the snow-ground interface. At 36.5 GHz, rough-surface brightness temperatures are lower than that of flat surface for both V-polarization and H-polarization. REFERENCES 1. C.M. Lam and A.

## Abstract A continuously tunable incoherent microwave photonic filter employing a tunable Mach‐Zehnder interferometer (MZI) as the slicing filter is studied. By incorporating the optical variable delay line (OVDL), the frequency spacing of the MZI can be tuned continuously, which in turn makes th
