Effective Radiating Area (ERA) and Beam Non-Uniformity Ratio (BNR)
SPATIAL PATTERN
The applicator produces a collimated cylindrical beam when measured at 5mm from the radiating surface with
distilled degassed water 30
o
C with line voltage variations of + 10 percent of rated value for the 5cm
2
transducer at 1
and 3MHz and the 2cm
2
transducer at 3MHz. At 1MHz the 2cm
2
transducer produces a diverging beam. The graph
on the following page is representative of a three dimensional plot of the beam at 5mm from the transducer surface.
