Novel Multi-Band SIW Antenna with Filtering Function [PDF]

Journal of Electromagnetic Engineering and Science
In this paper, the basic structure of a quad-band substrate-integrated waveguide (SIW) antenna with filtering characteristics is proposed. The proposed antenna consists of a four-slot SIW and a single-probe feed. Despite having a single feed, it was able

Quantum focusing conjecture and the Page curve

Journal of High Energy Physics, 2023
The focusing theorem fails for evaporating black holes because the null energy condition is violated by quantum effects. The quantum focusing conjecture is proposed so that it is satisfied even if the null energy condition is violated.

Failure Correction of a Linear Array of Coupled Parallel Vertical Dipole Antennas

Journal of Telecommunications and Information Technology, 2020
In this paper, a cuckoo search algorithm based on the combined characteristics of the brood parasite behavior and Levy flights is applied to correct the radiation pattern of a linear antenna array composed of parallel dipoles with faulty elements.

Synchrotron X-Ray Radiation-Induced Bystander Effect: An Impact of the Scattered Radiation, Distance From the Irradiated Site and p53 Cell Status

Frontiers in Oncology, 2021
Synchrotron radiation, especially microbeam radiotherapy (MRT), has a great potential to improve cancer radiotherapy, but non-targeted effects of synchrotron radiation have not yet been sufficiently explored.

A Dual-Band Patch Antenna with Combined Self-Decoupling and Filtering Properties and Its Application in Dual/Squad-Band Two-Element MIMO Array

Sensors
This paper proposes a dual-band patch antenna with combined self-decoupling and filtering properties, designed to suppress mutual coupling between two antenna elements both within the same dual-band and across different dual-bands. Initially, a dual-band

Classical soft graviton theorem rewritten

Journal of High Energy Physics, 2022
Classical soft graviton theorem gives the gravitational wave-form at future null infinity at late retarded time u for a general classical scattering. The large u expansion has three known universal terms: the constant term, the term proportional to 1/u ...

Wideband/Dual-Band Dielectric Filtering Inverted-L Antenna With Reflective and Quasi-Reflectionless Radiation Nulls

IEEE Open Journal of Antennas and Propagation
A class of dielectric filtering inverted-L antenna with reflective- and quasi-reflectionless-type radiation nulls is proposed to achieve wideband or dual-band operation.

Radiating stars with composite matter distributions

European Physical Journal C: Particles and Fields, 2021
In this paper we study the junction conditions for a generalised matter distribution in a radiating star. The internal matter distribution is a composite distribution consisting of barotropic matter, null dust and a null string fluid in a shear-free ...
