Broadband microstrip patch antenna
Electronics Letters, 1998 The characteristics of a rectangular microstrip antenna with an L-shaped probe are investigated. A foam layer with a thickness of around 10% of the wavelength is used as the supporting substrate. An impedance bandwidth of 35% and an average gain of 7.5 dBi can be achieved. The radiation pattern is stable across the passband.

Engineering Reports, Volume 8, Issue 7, July 2026.A compact printed wide‐slot antenna with a diamond‐shaped tuning stub and parasitic elements achieves an ultrawide impedance bandwidth of 256% (2.4–16.2 GHz). Its capacitive nature enables frequency shifts with dielectric variations, making it highly suitable for accurate, non‐invasive glucose sensing applications.

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.
