Summary
This study presents optically transparent mosaic frequency selective surfaces (MFSS) for smart city and vehicle applications. The novel design achieves wideband filtering with high optical transparency, showing promising potential for integrated photonic devices.
Area of Science:
- Electromagnetics and Photonics
- Materials Science
Background:
- Achieving optical transparency in wideband frequency selective surfaces (FSS) is crucial for smart city and automotive applications.
- Existing FSS designs often compromise optical transparency for desired electromagnetic performance.
Purpose of the Study:
- To assess the performance of optically transparent mosaic frequency selective surfaces (MFSS).
- To investigate the integration of Koch fractal and double hexagonal loop elements for wideband filtering and optical transparency.
Main Methods:
- Fabrication of MFSS on a polycarbonate substrate using conductive metallic elements.
- Analysis of both opaque and transparent MFSS performance, including electromagnetic response and optical transparency.
- Investigation of the unit cell's evolutionary influence on MFSS performance.
Main Results:
- Both opaque and transparent MFSS demonstrated wideband bandstop and bandpass responses.
- Low cross-polarisation levels (below -37 dB) were achieved.
- Transparent MFSS exhibited high optical transparency exceeding 70% with limited angular stability (25°).
- Good correlation between simulated and measured results for both opaque and transparent MFSS.
Conclusions:
- The proposed transparent MFSS offers a promising solution for applications requiring both wideband filtering and high optical transparency.
- The design shows potential for integration into smart windows, transportation services, and vehicle windows.
