A Monolayer Frequency-Selective Surface for Wideband Shielding Application with Adequate Out-of-Band Separation and Angular Stability

International Journal of Antennas and Propagation
In the proposed paper, a monolayer band-stop frequency-selective surface (FSS) is structured and analyzed for application in wideband shielding. The paper proposes an organized step-by-step method to design the frequency-selective surface (FSS) to ...

Polarization Insensitive and Angularly Stable Adaptive Frequency Selective Surface for Automated and on-Demand Electromagnetic Shielding

IEEE Access, 2023
A new adaptive frequency selective surface (AFSS) has been presented for electromagnetic (EM) shielding applications. Passive EM shields lack reconfigurability which severely limits their application.

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Design of miniaturized and highly selective frequency selective rasorber based on compact spiral resonator

Electronics Letters
A miniaturized, high‐selectivity, wideband A‐T‐A frequency selective rasorber (FSR) based on compact spiral resonators (CSR) is proposed here. The lossy layer of the FSR consists of the CSR and a Jerusalem cross, with four resistors soldered onto the ...
