Output description: The output waveform is continuous or pulsed as
programmed by the membrane panel control. In the pulse
mode the 1 or 3.2 MHz sine wave pulses
are modulated. The power level is adjusted by varying the
pulse amplitude. The pulse waveforms are shown

Ultrasonic Applicator Specifications:
Piezoelectric discs: The output transducer utilizes a barium titanate disc with
a specially coated face.
Individual Applicator Specifications:
Applicator Part Number Frequency Effective Radiating Area
ME 7513 1 or 3.2 MHz ±5% 5 cm² ±20%
Maximum Beam
Non–Uniformity Ratio: 6:1
Spatial Pattern: The applicator produces a collimated (cylindrical) beam
with an area of 5 cm², measured 5 mm from the ceramic
disc surface when the radiation is emitted into the
equivalent of an infinite medium of distilled water at 30° C.
The beam of the applicator is circular in all planes parallel
to the applicator face. A few inches from the face, it is a
single smooth bell-shaped curve. Nearer the face the
pattern varies more due to phase cancellations. Sample
curves measured in the far field from the surface are shown
in Figures 9.3 and 9.4.
