Study on Optimization of Different Characteristics of Novel Shaped FSS
This paper deals with the simulated as well as measured results of a Frequency selective surface with perfectly conducting novel shaped elements. This frequency selective surface (FSS) acts like a single band-reject filter. The proposed design has been investigated theoretically using Ansoft Designer® software in which the reflection and transmission bands have been predicted by the method known as Method of Moment. Further experimental investigation is performed using standard microwave test bench. In comparison to the reference square patched Frequency Selective Surface (FSS) without slot, this FSS with novel design can provide size reduction up to 84.98%. Efforts have been given to achieve optimized value for different characteristics of FSS.
A design approach for dual-polarized multiband frequency selective surfaces using fractal elements
We propose a technique for the design of multiband frequency selective surfaces (FSSs) that is based on the use of fractal screen elements. We demonstrate the design methodology by exploiting the self-similarity of the crossbar fractal to implement a tri-band FSS. Another benefit of this design approach, in addition to its multiband performance, is that the frequency response of both the TE and TM modes are exactly the same, owing to the symmetry in the tree-like fractal structure of the screen elements. Dielectric loading effects have been considered for practical implementation of designs with coverage exceeding two bands.
Collaborative Aircraft Design Methodology using ADAS linked to CEASIOM
The aircraft design stages, conceptual and preliminary, are necessarily collaborative bytheir very nature. An example design carried out in this paper brings the collaborativeaspects of design to l ...
