WebJun 28, 2024 · The peak gain of the designed antenna without metamaterial has been obtained −1.86 dB and the peak directivity is 8.37 dB. The gain and directivity have been enhanced to 4.52 dB and 12.35 dB respectively after the integration of metamaterial. WebJun 15, 2024 · The created 3D digital models were introduced into the acoustic simulation space to investigate the change in directivity and to study the effect of ear movement on localization. (2) For M. fuliginosus , an intact 3D digital model and a 3D digital model with the tragus removed were created to study the effect of the tragus on echolocation.
WebEarthquake directivity is the focusing of wave energy along the fault in the direction of rupture. This means that, exclusive of local site conditions such as soft soil, the stronger … WebDirectivity is defined as the ratio of the leakage of the incident signal to the fully reflected signal. The lower the leakage signal, the higher the accuracy of the reflection measurement. Two devices that may be used to separate the two …
