Classic V8 engines have a very distinct sound that modern engines seem to have lost over the years. How did automakers achieve this sound?

Abstract: We present a self-aligned fabrication method developed for three-dimensional (3-D) microscale hemispherical shell resonators with integrated capacitive transducers and a center post for ...

Abstract: The resonant modes of the rectangular dielectric resonator antenna (DRA) are systematically investigated. Their resonance frequencies are accurately determined by exploring the radar cross ...
