“…The long-range detection is favored by the low-frequency range (1–100 kHz). Meanwhile, high ultrasonic frequency for acoustic imaging has also been placed between 100 kHz and 2 MHz [ 47 ]. Since resolution and frequency are directly related, 100 kHz is therefore selected as the working frequency of the proposed array.…”

“…Based on this frequency and the space limitation on the hosting surface of the mine hunter for the proposed array, the aperture width is restricted to a maximum of 33 cm, which also falls within the size range recommended for underwater acoustic imaging [ 47 ]. In addition, the pitch is maintained at less than a half wavelength while the kerf is also fixed at 0.5 mm to achieve the wider element size needed for the target high-power output.…”

“…3D model of PMUT element with first layer and third layer (top and bottom electrode) were composed by copper, second layer with blue region is the active material layer and fourth layer is the silicon dioxide as supporting layer.This structure was simulated in a water medium setting with six different active materials which were PZT-5A, PZT-5H, aluminium nitride, lithium niobate, quartz, and zinc oxide. The designed structure was modelled referring parameters to the existing PMUT basic structure Akasheh, Myers, Fraser, Bose & Bandyopadhyay, 2004;Ahmad, A. Manaf, Yaacob & A. Rahman, 2017) by using finite…”
