Physico‐Chemical, Microstructural, and Cooking Characteristics of Faba Bean (Vicia faba) Varieties From New Zealand

open access: yesLegume Science, Volume 7, Issue 3, September 2025.
ABSTRACT This research examines the physical and microstructural properties of New Zealand faba beans (Vicia faba), with a focus on their influence on swelling, hydration, and cooking characteristics. Four native varieties (Early Long Pod, Evergreen, Coles Dwarf, and Janet) were studied.

On‐chip GaAs‐based dual‐band bandpass filters/isolators (DBPFIs)

open access: yesElectronics Letters, 2023
MMIC co‐designed RF components exhibiting the collocated RF signal processing actions of a dual‐band bandpass filter and an RF isolator (DBPFI) are presented. They are based on in‐parallel cascaded bandpass filters/isolators that operate at two different

An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

open access: yesAdvanced Engineering Materials, Volume 27, Issue 15, August 2025.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

A simplified algorithm for leaky network analyzer calibration [PDF]

open access: yes, 1995
A new algorithm for network analyzer calibration is presented. The error model includes leakage effects and can be applied to a general n-port NWA. The 2-port 16-term model becomes a special case of this new technique which is also hopefully suitable for

A Temperature‐Dependent Linear RF Switch Model for Common‐Gate High‐Frequency GaN HEMT Transistors

open access: yesInternational Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 38, Issue 4, July/August 2025.
ABSTRACT This paper reports a temperature dependent high frequency monolithic microwave integrated circuit (MMIC) linear radio frequency (RF) switch modeling technique for gallium nitride (GaN) RF switch transistors. Linear model extraction has primarily focused on common source (CS) RF transistors.
