surface is smaller than that of the flat surface. That is because the Brewster angle between ground and snow is 50Β°. The 50Β°angle in snow corresponds to 35Β°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-a

An integrated photonic microwave reconfigurable filter was proposed and realized incorporating a tunable polymeric ring resonator. Its passband could be shaped electrically by shifting the resonant peaks of the resonator via the thermo-optic effect. As for the achieved performance, the center freque
A new broadband omnidirectional U-shaped metal-plate monopole antenna has been proposed. The antenna is easy to implement at low cost by bending a rectangular metal plate into a U-shape. Prototypes of the antenna have been constructed and studied. Good omnidirectional radiation patterns with gain va
A novel tunable and reconfigurable microwave photonic filter based on two cascaded modulators and a dispersive medium is proposed, theoretically discussed and experimentally demonstrated. A singlewavelength LD and a modulator (either a Mach-Zehnder modulator or a phase modulator which can avoid the
## Abstract A continuously tunable incoherent microwave photonic filter employing a tunable MachβZehnder 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
