New paper “Three-Dimensional Fully Metallic Dual Polarization Frequency Selective Surface Design Using Coupled-Resonator Circuit Information”
We are pleased to announce that our research group has achieved a publication in the prestigious journal ‘IEEE Transactions on Antennas and Propagation’. The paper entitled ‘Three-Dimensional Fully Metallic Dual Polarization Frequency Selective Surface Design Using Coupled-Resonator Circuit Information’ highlights a new approach to analyse coupled resonator circuits in order to design and fabricate a frequency selective surface (FSS) with dual polarization.
The proposed filter structure consists of unit cells with resonators coupled primarily along the z-direction and periodically repeated in the xy-plane. This design allows the evanescent electromagnetic field to pass through the metallic structure in the desired frequency band for both polarisations. The paper presents a fabricated and measured FSS prototype, showing good agreement between simulation results and the final prototype.
These filters are especially useful in output stages of data transmitters, offering narrowband transmission. Also, these frequency selective surfaces (FSS) have a place in specific applications, such as space and military environments, highlighting the flexibility and adaptability of FSS to large areas and curved surfaces.
The proposed all-metal FSS, as presented in this work, shows promising applications in space missions due to its robustness in extreme conditions and its high quality factors.
