Summary Frequency‐domain detection stands as a critical method in remote geophysical exploration; however, its practical application is constrained by the considerable size of requisite instrumentation. In this paper, we present compact frequency domain electromagnetic system. The integration intelligent power devices and novel hardware architecture substantially diminishes system's dimensions, thereby enhancing portability. Furthermore, system design incorporates sinusoidal pulse width...
Abstract Metalens are planar lenses composed of the subwavelength arrays, which have unconventional and versatile functionalities to manipulate light fields compared with traditional lens. It is noted that most metalens designed in a monochromatic mode visible or mid-infrared range (mid-IR), however, broadband needed many practical applications, such as spectroscopy, sensing, imaging. Here, we design demonstrate achromatic dielectric mid-IR 4 µm–5 µm for near diffraction-limited (1.0 λ )...
Orbital angular momentum of light has attracted great attention in recent years. Optical ferris wheel, composed the superposition different orbital-angular-momentum modes, further broadens application orbital many fields. Here, we experimentally demonstrate a simple way to produce optical wheel with controllable modes using mask spiral arrays. We show that can be rotated by adjusting arrays, and rotation angle is studied analytically experimentally. Our technique shows advantages wide...
The current inverter is the core component of helicopter transient electromagnetic (HTEM) detection system. It should meet concerns low loss, high power, and fast turn-OFF time. This article proposes a new circuit topology based on nine-level technology to overcome drawbacks typical PWM (pulse width modulation) inverters, such as switching losses harmonics. overcomes shortcomings traditional single constant voltage clamp in which time not adjustable. Using an with proposed able avoid complex...
