This paper presents a multi-Helmholtz unit series–parallel acoustic metamaterial with segmented noise control effect designed by taking advantage of the adjustable frequency band an metamaterial, aiming to change main spectrum characteristics under different driving conditions military equipment such as tanks. Based on transfer matrix method, theoretical model that can predict hybrid structure multiple Helmholtz resonator (HR) units is established, and its feasibility verified through finite...
Based on the parametric oscillation process, we demonstrate dual-axis phase-sensitive demodulation (PSD) and single-axis phase-insensitive (PISD) for atomic magnetometer in an situ nuclear magnetic resonance (NMR) detection system, which can separate precession signals of NMR from oscillating fields. The two orthogonal fields be detected simultaneously independently by selecting optimal phases with traditional PSD method. response modulation demodulated high order harmonic are evaluated, is...
