Tunable spin-wave delay line based on ferrite and vanadium dioxide [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамика, 2022 One of the key elements for modern microwave circuits is a delay line, which is widely utilized for the signal generation as well as processing. Spin-wave delay lines based on ferrite films provide a high delay time and small dimensions.

Improved Empirical Formula Modeling Method Using Neuro-Space Mapping for Coupled Microstrip Lines
Micromachines, 2023 In this paper, an improved empirical formula modeling method using neuro-space mapping (Neuro-SM) for coupled microstrip lines is proposed. Empirical formulas with correction values are used for the coarse model, avoiding a slow trial-and-error process ...

Microwave Dielectric Heating of Drops in Microfluidic Devices [PDF]
, 2009 We present a technique to locally and rapidly heat water drops in microfluidic devices with microwave dielectric heating. Water absorbs microwave power more efficiently than polymers, glass, and oils due to its permanent molecular dipole moment that has ...

Optimized microwave illusion device
Scientific Reports, 2017 AbstractWe report the design, fabrication and experimental verification of an illusion device working at microwave frequencies. A two dimensional topology optimization procedure is employed to find the binary layout of a dielectric coating that, when wrapped around a metallic cylinder, mimics the scattering from a predefined, arbitrarily-shaped ...
