Discovery of a Rich Population of Compact Hub-filament Systems in a Single Star-forming Complex
The Astronomical JournalWe report the discovery of 45 compact hub-filament systems (HFSs; median size ∼2.4 pc) in infrared-dark clouds (IRDCs) in the W33 complex, located at the junction of the Scutum and Norma spiral arms.

Design of Wideband Antenna for Millimeter Waves Using HFSS
International Journal for Research in Applied Science and Engineering Technology, 2021 This paper reviews the objectives and requirements of wideband antenna for millimeter-wave applications using HFSS software (Ansys HFSS V.15.0). In modern era, all wireless devices are multipurpose and versatile, so this requires a wideband antenna to perform different tasks.

Study On Waveguide Slots Using Hfss
, 2017 In this paper we present the design of WR975 waveguide using HFSS simulation software. The slot present in the wave guide will cause the waveguide to radiate and act as an antenna. Another slot is also kept to check the results with a single slot and compared.
