Frequency and polarisation selective surface for sub‐millimetre wave atmospheric remote sensing

open access: yesIET Microwaves, Antennas & Propagation, 2023
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.

SWITCHABLE SPLIT-RING FREQUENCY SELECTIVE SURFACES [PDF]

open access: yesProgress In Electromagnetics Research B, 2008
Tunable frequency selective surfaces (FSSs) based on split ring resonators (SRRs) are presented. Tuning performance is achieved by means of several on/off switches placed between the rings of each SRR element. The band-stop FSS response is dynamically tuned to different frequency bands at different switching states.

Synthesis of a polarisation‐rotating surface with reflective filtering response based on orthogonally inserted coupled slot‐lines

open access: yesIET Microwaves, Antennas & Propagation, 2023
In this article, a three‐dimensional polarisation‐rotation surface (PRS) with reflective filtering response based on two orthogonally inserted coupled slot‐line is investigated, which can reflect a vertically/horizontally polarised incident wave by 90 ...

Traditional Frequency Selective Surface versus Substrate Integrated Waveguide Frequency Selective Surface [PDF]

open access: yesUniversal Journal of Communications and Network, 2014
This paper is devoted to analysis design and fabrication of both traditional and substrate integrated waveguide (SIW) frequency selective surfaces (FSS) of square elements and square lattice. The transmission loss is studied for different angle of incidence; normal, thirty, forty five and sixty degrees.

Ultra-Thin Metasheet for Dual-Wide-Band Linear to Circular Polarization Conversion With Wide-Angle Performance

open access: yesIEEE Access, 2020
Satellite communication systems require dual-band circularly polarized (CP) waves to integrate receiving and transmit antennas into one dual-band terminal. Polarization converters play an important role in such a scenario to convert the incoming linearly

Proposed Technique of Analysis for Absorber/Transmitter Frequency Selective Surfaces

open access: yesJournal of Microwaves, Optoelectronics and Electromagnetic Applications, 2021
In this paper, we propose a simple technique to analyze absorber/transmitter frequency selective surfaces (FSS). The structure is formed by two FSS, one resistive and one conductive. Both FSS are printed on an FR4 dielectric substrate.

Finite frequency selective surface modelling

open access: yesThe 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014
In this paper we describe the development of an electromagnetic modelling technique to investigate edge illumination effects on finite size FSS performance. The work extends the commonly used unit cell approach and models the FSS as a linear array with Gaussian beam excitation.

Inductive Frequency Selective Surface: An Application for Dichroic Sub-Reflectors

open access: yesIEEE Access, 2020
An Inductive Frequency Selective Surface (IFSS) self-standing dichroic sub-reflector is presented, which allows the transmission of two frequency bands and reflection of a third band. The operating frequency of the sub-reflector is designed to work at Ku,
