“…Additionally, in order to obtain desirable FSS behaviours, intelligent genetic algorithm (GA) is utilised [12][13][14][15][16], and full wave solvers are incorporated in optimisation procedure to calculate frequency responses accurately. Although optimisation goals could be achieved as far as possible, physical understanding of working principles are less presented in this method.…”

In this study, a promising application of frequency selective surface (FSS) operating in circular polarisation is analysed and designed. Both magnitude and phase consistencies between transverse electric (TE) and transverse magnetic (TM) waves are emphasised, especially transmission phase agreement. Equivalent circuit model (ECM) provides a deep physical insight into phase discrepancy between TE and TM waves. The effects of geometrical parameters of FSS on magnitude and phase consistencies are also investigated by ECM. Additionally, an optimisation process is utilised to obtain desired frequency responses for multi‐layer FSS design. This process involves iterative correction and update of coarse circuit model on the basis of a few accurate full wave simulations. Moreover, a dual‐layer square slot FSS is efficiently designed using this optimisation method. Finally, a prototype of the optimised dual‐layer square slot FSS is fabricated and tested to validate the simulated results.

A novel Frequency and Polarisation Selective Surface (FPSS) is proposed, which separates two adjacent bands with a narrow transition zone by the staggered separation scheme and is suitable for atmospheric remote sensing. The traditional FSS is transparent in a particular frequency band for both the TE and TM polarisations, while it is opaque in another band for both orthogonal polarisations. The FPSS is introduced in a new splitting scheme that operates above 300 GHz. The channel 420–430 GHz of the TE polarisation and the channel 360–400 GHz of the TM polarisation transmit in the FPSS. In contrast, the band 360–400 GHz of the TE polarisation and the channel 420–430 GHz of the TM polarisation are reflected. The water vapour and the oxygen profiles are detected by the 380 GHz band and the 425 GHz band, respectively. The insertion loss is lower than 1 dB, and the reflection band rejection is superior to 10 dB in the experiment, which determine the sensitivities of the bright temperature by 1.5 (RMS K). The scattered wave of the FPSS is calculated through the far field pattern, the maximum of which is about 5%. The side effect of the scattered wave is able to be ignored in the optical path.
