Transmission Properties of the oscillating delta-function potential

, 2001
We derive an exact expression for the transmission amplitude of a particle moving through a harmonically driven delta-function potential by using the method of continued-fractions within the framework of Floquet theory.

Inline Waveguide Pseudo-Elliptic Filters Using Non-Resonating Modes With Folded-Waveguide Resonators

IEEE Access, 2021
In this paper, a new structure to implement inline waveguide pseudo-elliptic filters using folded-waveguide (FWG) resonators along with non-resonating modes has been proposed. The basic structure is an FWG resonator fed by a rectangular waveguide through

Miniaturised microstrip dipexers for WiMAX applications [PDF]

, 2008
Miniaturised microstrip diplexer and bandpass filters using single ring resonators with good transmission and reflection characteristics on each channel for WiMAX applications have been presented. The size of the proposed diplexer is reduced.

Physical Meaning of Zeros and Transmission Zeros from Bond Graph Models [PDF]

IFAC Proceedings Volumes, 1996
Abstract The power flow within a physical system determines its dynamic behaviour, of which zeros are an important characteristic. For this, the bond graph representation is used to visualize the paths of power flow and the energy interaction between the elements.

Analysis and implementation of 3D bandpass frequency selective structure with high frequency selectivity

Electronics Letters, 2017
A novel 3D frequency selective structure (FSS), exhibiting bandpass filtering response with high frequency selectivity, is presented. In each unit cell, multiple resonators are constructed to provide multiple transmission zeros/poles.

Multitransmission Zero Dual-Band Bandpass Filter Using Nonresonating Node for 5G Millimetre-Wave Application

Active and Passive Electronic Components, 2018
A planer millimetre-wave dual-band bandpass filter with multitransmission zeros is proposed for 5G application. This filter includes two dual-mode open-loop resonators.

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity

Molecular Oncology, EarlyView.
Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a

Wideband Bandpass Filters Using a Novel Thick Metallization Technology

IEEE Access, 2020
A new class of wideband bandpass filters based on using thick metallic bars as microwave resonators is presented in this work. These bars provide a series of advantages over fully planar printed technologies, including higher coupling levels between ...
