Millimeter‐Wave Antennas: A Comprehensive State‐of‐the‐Art Review of Design Approaches, Operating Bands, Challenges, and Applications in Body‐Centric and Emerging Systems

open access: yesRadio Science, Volume 61, Issue 5, May 2026.
Abstract This paper reviews and classifies more than 120 recent contributions on millimeter‐wave (mm‐wave) antennas, with emphasis on their operating bands, design methods, and application domains. It surveys the main mm‐wave frequency ranges and their use in 5G/6G communications, radar and sensing, biomedical and body‐centric systems, imaging, and ...

Extreme Rhythm Keeping in Long‐Range Slow Click Communication of Sperm Whales

open access: yesAnnals of the New York Academy of Sciences, Volume 1559, Issue 1, May 2026.
In this study, we show that male sperm whales produce low‐frequency slow clicks at low repetition rates with extreme source levels > 200 dB re 1 µPa (pp), making them the loudest mammalian communication signal, with an estimated active space of ∼70 km.

An Overview of Multipath TCP.

open access: yeslogin Usenix Mag., 2012
TCP has remained mostly unchanged for 20 years, even as its uses and the networks on which it runs have evolved. Multipath TCP is an evolution of TCP that allows it to run over multiple paths transparently to applications. In this article, we explain how Multipath TCP works, and why you should want to start using it.

Simulation of an automatically-controlled STOL aircraft in a microwave landing system multipath environment [PDF]

open access: yes
The simulated response is described of a STOL aircraft to Microwave Landing System (MLS) multipath errors during final approach and touchdown. The MLS azimuth, elevation, and DME multipath errors were computed for a relatively severe multipath ...

On OFDM Ranging Performance Degradation in Multipath Scenarios: Bias and Misspecified Cramér–Rao Bounds

open access: yesIEEE Access
Multipath propagation represents a dominant error source limiting the accuracy of radio-based ranging and positioning in urban environments. Conventional ranging estimators typically estimate only the range of the first arriving path while neglecting the

Multipath errors in range rate measurement by a TDRS/VHF - GRARR [PDF]

open access: yes
Range rate errors due to multipath reflection are calculated for a tracking and data relay satellite system using the VHF Goddard range and range rate (GRARR) system. At VHF the reflection is primarily specular, and the strength of the multipath relative
