摘要： A filter assembly and a method for filtering electromagnetic radiation are provided. The filter assembly includes a dielectric layer having a first side and a second side. The filter assembly further includes a first conductive layer disposed on the first side of the dielectric layer. The filter assembly further includes a second conductive layer disposed on the second side of the dielectric layer. The filter assembly further includes a voltage source electrically coupled to the first and second conductive layers. The voltage source is configured to generate a first voltage signal that adjusts a dielectric constant value of the dielectric layer to a first desired dielectric constant value to filter electromagnetic radiation impinging on the first conductive layer. The voltage source is further configured to generate a second voltage signal that adjusts the dielectric constant value of the dielectric layer to a second desired dielectric constant value to filter electromagnetic radiation impinging on the first conductive layer.

摘要： The present invention relates to an Electro-Optical (E-O) crystal elements, their applications and the processes for the preparation thereof. More specifically, the present invention relates to the E-O crystal elements (which can be made from doped or un-doped PMN-PT, PIN-PMN-PT or PZN-PT ferroelectric crystals) showing super-high linear E-O coefficient yc, e.g., transverse effective linear E-O coefficient yTc more than 1100 pm/V and longitudinal effective linear E-O coefficient ytc up to 527 pm/V, which results in a very low half-wavelength voltage Vtx below 200V and Vtx below about 87V in a wide number of modulation, communication, laser, and industrial uses.
