Advanced Photonics Research, Volume 7, Issue 3, March 2026.Terahertz microscale silicon waveguides can be wholly unclad, making it possible to interact with guided waves contactlessly via evanescent fields. We exploit this with conductive walls that enforce a movable field‐null upon modal fields, enabling tunable dispersion and cutoff similar to a fiber squeezer, albeit without physical contact.

Adaptive Orthogonal Frequency Division Multiplexing Schemes
, 1998 This paper investigates the upper-bound performance of subband-adaptive Orthogonal Frequency Division Multiplexing (OFDM) transmission in a time-dispersive channel and the feasibility of blind modulation scheme detection algorithms not requiring modulation scheme signalling information.

Spectral Efficiency for Orthogonal Frequency Division Multiplexing
International Journal of Advanced Research in Science, Communication and TechnologyOrthogonal Frequency Division Multiplexing (OFDM) is a special form of multicarrier modulation (MCM) with heavily spaced subcarriers as well as overlapping spectra was patented in the United States of America in 70s. Orthogonal Frequency Division Multiplexing has been popularly utilized in modern days due to its ability for spectral efficiency and ...

Recent Advances in Decoupling Strategies for Soft Sensors
Advanced Science, Volume 13, Issue 17, 23 March 2026.This review provides an overview of recent advances in decoupling strategies for soft sensors. It summarizes single‐modal sensors that are insensitive to stretching, bending, crosstalk, and other environmental interferences, and highlights emerging multimodal decoupling methods enabled by spatiotemporal information and machine learning.
