Linearly polarized GHz magnetization dynamics of spin helix modes in the ferrimagnetic insulator Cu$_{2}$OSeO$_{3}$ [PDF]

open access: yes, 2017
Linear dichroism -- the polarization dependent absorption of electromagnetic waves -- is routinely exploited in applications as diverse as structure determination of DNA or polarization filters in optical technologies.

Microwave-photonic filters

open access: yes2016 German Microwave Conference (GeMiC), 2016
Microwave-photonic filters (MPF) can overcome the limitations of electrically implemented counterparts. MPF can have a very broad bandwidth, they are tunable and even the filter shape can be changed by programming. Here we review our recent results in the implementation of MPF.

Parametrically enhanced bandpass filters

open access: yesIET Microwaves, Antennas & Propagation, 2021
This paper proposes a technique to enhance the quality factor (Q) of a resonator, which can then be used to realise bandpass filters (BPFs) with reduced insertion loss (IL) and improved passband selectivity.

Optimisation‐based design of transversal signal‐interference microwave bandpass and lowpass filters with extended stopband

open access: yesIET Microwaves, Antennas & Propagation, 2021
Generalised bi‐path stepped‐impedance‐line signal‐interference bandpass and lowpass transversal filtering sections (TFSs) with increased stopband bandwidth above the main transmission band are presented.

On Optimal Detection of Point Sources in CMB Maps

open access: yes, 2002
Point-source contamination in high-precision Cosmic Microwave Background (CMB) maps severely affects the precision of cosmological parameter estimates. Among the methods that have been proposed for source detection, wavelet techniques based on ``optimal''

Potential applications of microstrip devices with traveling wave resonators [PDF]

open access: yesТехнологія та конструювання в електронній апаратурі, 2013
The shortcomings of the known microwave filters in microstrip lines are considered, the advantages of the use of directional traveling-wave filters in microstrip performance and examples of their potential applications are shown.

Microwave Components with MEMS Switches [PDF]

open access: yes, 2000
RF MEMS switches with metal-metal contacts are being developed for microwave applications where broadband, high linearity performance is required. These switches provide less than 0.2 dB insertion loss through 40 GHz. This paper describes the integration

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.
