Radome Diagnostics: utilizing Source Reconstruction based on Surface Integral Representations
… reconstruction method with great potential in radome diagnostics is presented. A radome is a cover that encloses an antenna in order to protect it from environmental influences. Radome diagnostics are acquired in the design process, the delivery control, and in performance verification of …

Retrieval of equivalent currents by the use of an integral representation and the extinction theorem --- radome applications
… values in the inversion process. A nose-cone radome is diagnosed by recreating the equivalent surface currents on its surface from measured near fields. It is shown how the radome interacts with the field, creating beam deflection, pattern distortion, etc. The phase shift of the field due to …

Nondestructive Evaluation of Zirconium Phosphate Bonded Silicon Nitride Radomes
… of radar-guided missiles have created a need for radome materials with improved strength, toughness, and thermal shock capabilities. Zirconium phosphate bonded silicon nitride (Zr-PBSN), which has a low and thermally stable dielectric constant, high rain erosion resistance and a low-cost …

Design of Microwave Front-End Narrowband Filter and Limiter Components
… EM aperture that can be integrated into a radome structure that shields enclosed antenna(s) from incident energy. Active elements are plasma-shells that are electrically excited by frequency selective surfaces (FSS) that are transparent to the frequency band of interest. The result is …

Antenna systems research
… as RCS reduction due to construction errors and radome covers Publications relating to a number of other miscellaneous antenna investigations are also included in this thesis. Among these are descriptions and performance details of choked waveguide and printed dipole feeds for parabolic reflector …
