Reconfigurable Spoof Plasmonic Skyrmion Electronics for Deformation‐Invariant Multimode Sensing
Advanced Science, Volume 13, Issue 34, 19 June 2026.A flexible multimode sensor based on capacitively loaded spoof plasmonic skyrmions enables deformation‐invariant dielectric sensing with ultra‐compact size and high Q‐factor. Near‐equidistant resonances remain stable under shape change and bending, while capacitor loading improves bending robustness and multimode sensitivity, highlighting strong ...

Small Microstrip Patch Antennas
Electronics Letters, 1995 As stated in Chapter 1, one of the many advantages of microstrip patch technology over its competitors is its low profile and hence small volume. Another key advantage of this printed antenna is the relative ease in which it can be connected to the feed network, as was highlighted in Chapter 2.

Low Insertion‐Loss High Power X‐Band SPDT Transmit/Receive Switches in 250 nm GaN HEMT
Microwave and Optical Technology Letters, Volume 68, Issue 6, June 2026.ABSTRACT We present three X‐band transmit/receive (T/R) switches utilizing single‐pole double‐throw (SPDT) structures in 250 nm GaN HEMT technology. The first T/R switch was designed to achieve low insertion loss by constructing the SPDT structure with a series λ/4 transmission line (T‐line) and meticulously selected two HEMT switches in parallel for ...

Loss Compensation and Coherent Virtual Absorption via Virtual Complex Frequency Wave Excitation
Nanophotonics, Volume 15, Issue 9, 13 May 2026.By establishing a mathematical bridge between real and complex frequencies, we present a general method for complex frequency wave excitation to obtain all electromagnetic responses at complex frequencies. Using properties of complex frequency waves, we compensate for the propagating loss of point sources and surface plasmon polaritons.
