Optimal time-domain combination of the two calibrated output quadratures of GEO 600 [PDF]

, 2005
GEO 600 is an interferometric gravitational wave detector with a 600 m arm-length and which uses a dual-recycled optical configuration to give enhanced sensitivity over certain frequencies in the detection band. Due to the dual-recycling, GEO 600 has two

Magnetically tunable multi-band near-field radiative heat transfer between two graphene sheets

, 2018
Near-field radiative heat transfer (NFRHT) is strongly related with many applications such as near-field imaging, thermos-photovoltaics and thermal circuit devices. The active control of NFRHT is of great interest since it provides a degree of tunability

Dual‐band single‐layer substrate‐integrated waveguide filtering antennas with independently controllable bands

IET Microwaves, Antennas & Propagation
A novel design method of dual‐band single‐layer substrate‐integrated waveguide (SIW) filtering antennas with independently controllable bands is proposed in this paper. The basic two‐pole dual‐band filtering antenna is proposed by a dual‐mode rectangular

Dual-band transmission polarization conversion metasurface and its reconfigurable-phase design

Results in Physics
Although abundant transmission polarization conversion metasurfaces (T-PCMs) have been reported, a dual-band T-PCM has only received little attention. Moreover, a reconfigurable-phase design of the T-PCMs is limited to a single-frequency band operation ...

Dual-Band and Dual-Polarized Antenna System Design for Ka-Band Applications

2024 IEEE International Symposium on Antennas and Propagation and INC/USNC‐URSI Radio Science Meeting (AP-S/INC-USNC-URSI)
This study presents a dual-band dual-circular polarization feed chain for Ka-band applications such as satellite communication systems. The proposed feed chain consists of a Tx-Rx corrugated antenna, iris polarizer, rectangular-to-square transition, and square-to- circular transition.

Design and simulated characterization of the dual-band polarizer based on metasurface structure

AIP Advances
Dual-band polarizers must simultaneously exhibit high transmittance and bandwidth efficiency in fields such as polarization navigation and efficient detection. However, in most studies, the detection of dual bands is inefficient.
