The absolute position of a resonance peak [PDF]

, 1993
It is common practice in scattering theory to correlate between the position of a resonance peak in the cross section and the real part of a complex energy of a pole of the scattering amplitude.

Dual‐band bandpass filter based on a single triple‐mode ring resonator

Electronics Letters, 2016
A novel dual‐band bandpass filter (BPF) based on a single triple‐mode ring resonator is proposed. The proposed BPF could provide three transmission poles for each passband to improve operating bandwidth.

Wave excitation and dynamics in non-Hermitian disordered systems

Physical Review Research, 2022
Dynamic and steady-state aspects of wave propagation are deeply connected in lossless open systems in which the scattering matrix is unitary. There is then an equivalence among the energy excited within the medium through all channels, the Wigner time ...

Dual-Polarized Frequency Selective Rasorber With Two Transmission Bands

IEEE Access, 2019
This paper presents a novel dual-polarized frequency selective rasorber (FSR) with two transmission bands and two absorption bands. The FSR is a 2-D structure which is composed of a lossy and a lossless frequency selective surface (FSS) layer.

Centrifugally-cast concrete poles with non-metallic reinforcement

Građevinar, 2021
The article describes the testing of poles for electric power transmission lines, which are made of centrifugally-cast concrete and ultra-high strength concrete, and which are prestressed with Carbon Fibre Reinforced Polymer tendons (CFRP). The presented

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.
