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.

Microwave Diplexer Purely Based on Direct Synchronous and Asynchronous Coupling [PDF]
Radioengineering, 2016 A diplexer realized purely based on direct coupling is presented. No cross-coupling is involved in the design process. The microwave diplexer is achieved by coupling a dual-band bandpass filter onto two individual channel filters.
