Compact microstrip lowpass filter

Electronics Letters, 2004
A novel compact microstrip lowpass filter using the slow-wave resonator is described. This filter has the advantages of low insertion loss in the passband, high and wide rejection in the stopband and compact size. A demonstration filter is designed, fabricated and tested. Theoretical and experimental results are presented.

Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.
