Polarized infrared emission using frequency selective surfaces.
An emission frequency selective surface, or eFSS, is made up of a periodic arrangement of resonant antenna structures above a ground plane. By exploiting the coupling and symmetry properties of an eFSS, it is possible to introduce polarization sensitive thermal emission and, subsequently, coherent emission. Two surfaces are considered: a linearly polarized emission surface and a circularly pola...
متن کاملDual-band Circularly Polarized Microstrip Antenna with Small Frequency Ratio
A compact single-feed dual-band circularly polarized (CP) microstrip antenna is evaluated numerically and experimentally. The dual-band performances with small frequency ratio (about 1 : 1.1) are achieved by a circular patch and a narrow annular-ring, which have small difference in radius. The CP characteristics are achieved by an unequal cross-slot embedded in the circular patch and two orthog...
متن کاملA New Implementation of Frequency Selective Surface Cloak for Cylindrical Structures
The main purpose of this paper is to design, implement and measure a new sample of mantle cloak. A new method called mantle cloak is introduced by cloaking an object by a single, conformal meta-surface which can drastically suppress the scattering of the desired object. In this paper, a grid lattice is placed around a dielectric object as the cloaking structure. Previously, this FSS has been ut...
متن کاملThe NASA Dual-Frequency Dual-Polarized Doppler Radar (D3R) System For GPM Ground Validation
Following on the successful introduction of single-frequency (Ku-Band) weather radar onboard the Tropical Rain Measuring Mission (TRMM) satellite in 1997, the Global Precipitation Measurement (GPM) mission attempts to advance further the goal of making global scale precipitation observations by deploying the next generation of satellite-borne weather radars. The GPM satellite will carry a Ka-Ku...
متن کاملMeasurement of Singly Polarized P N Collisions at Hera
A summary is given on the physics potential of measuring singly polarized proton–nucleon collisions using a polarized internal target in the 820 GeV HERA proton beam. This summary is based upon talks given at the 2nd Meeting on Possible Measurements of Singly Polarized p p and p n Collisions at HERA, which was held at DESY Zeuthen from August 31 to September 2, 1995 as a follow-up to the Worksh...
