Spheroidal ambisonics: Spatial audio in spheroidal bases [PDF]
JASA Express Letters, 2021 Ambisonics is an established framework to capture and reproduce spatial sound fields based on the spherical harmonics representation [Gerzon (1973). J. Audio Eng. Soc. 21(1), 2–10]. A generalization—spheroidal ambisonics—based on spheroidal wave functions is proposed for use with spheroidal microphone arrays.

A review on the preparation and characterization methods of spherical explosive crystals
Journal of Materials Research and Technology, 2023 Spherical explosive crystals refer to explosives with a spherical morphology. Compared to polyhedral explosive crystals, spherical explosive crystals do not have sharp edges or corners, and have a lower probability of generating hot spots due to the ...
