A Broadband Magnetic Coupling Microstrip to Waveguide Transition Using Complementary Split Ring Resonators

open access: yesIEEE Access, 2019
A novel broadband microstrip to waveguide transition is proposed in this paper. A microstrip circuit is inserted into a waveguide along the axis of the broadside wall, and the referred waveguide is WR-90 standardized rectangular waveguide. The microstrip

EMC filter based on complementary split-ring resonators for audio applications [PDF]

open access: yes, 2009
Filters based on complementary split-ring resonators present a large notch attenuation at the resonant frequency. An application of these very low cost filters to an audio system interfered by a mobile phone is presented in this paper.Peer ...

Dual Polarized Reconfigurable Frequency Selective Surfaces [PDF]

open access: yes, 2013
Novel band-stop active frequency selective surfaces (FSS) capable of modifying their response for different polarizations are proposed. Geometries based on full rings, and split rings are employed.

Circulating tumor cell viability during and after radiotherapy mirrors treatment response in cancer patients

open access: yesMolecular Oncology, EarlyView.
Radiotherapy (RT) response depends on the DNA repair capacity of tumor and host cells. We show that circulating tumor cell (CTC) counts and apoptosis rates before and after RT predict treatment response and outcome, which can be accessed via easily accessible liquid biopsy approaches. Created in BioRender. Wikman, H.

Recent Advances in the Modeling of Transmission Lines Loaded with Split Ring Resonators

open access: yesInternational Journal of Antennas and Propagation, 2015
This paper reviews the recent advances in the modeling of transmission lines loaded with split ring resonators (SRRs). It is well known that these artificial lines can exhibit a negative effective permeability in a narrow band above the SRR fundamental ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Design of novel highly sensitive sensors for crack detection in metal surfaces: theoretical foundation and experimental validation

open access: yesScientific Reports, 2023
The application of different types of microwave resonators for sensing cracks in metallic structures has been subject of many studies. While most studies have been focused on improving the sensitivity of planar crack sensors, the theoretical foundation ...

Enhancing Complementary Split Ring Resonators Performance for Atherosclerosis Diagnosis

open access: yes2024 IEEE Biomedical Circuits and Systems Conference (BioCAS)
This paper presents an improved complementary split ring resonator (CSRR) used as a non-invasive microwave sensor for in-vivo detection of atherosclerotic plaques. The sensor geometry was optimized on low-loss substrates to enhance the trade-off between the energy stored in the resonator and the energy radiated into the biological tissue.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.
