1921 Physical Rev. 18 263 For the weaker [magnetic] fields there is a decided curvature in the lines which gradually smooth out into practically straight lines. It is in this lower region that the ‘square law’, proposed by Sir J. J. Thomson, holds.

1926 R. W. Hutchinson First Course Wireless 69 Another type of variable condenser is known as the square law condenser, and in the best wireless receivers it has replaced the ordinary form.

1930 B.B.C. Year Bk. 452 Square law condenser, a variable condenser in which the angle of rotation is proportional to the square of the capacity, and thus proportional directly to the change in wave-length.

1932 B.B.C. Year Bk. 359 An instrument known as a volume indicator, which is a square-law device with a calibrated attenuator preceding it.

1932 B.B.C. Year Bk. 365 A square-law meter, for instance, on moderately weak passages hardly moves at all.

1945 Electronic Engin. 17 734/2 The valve will work satisfactorily as a square law rectifier.

1958 W. T. O'Dea Social Hist. Lighting i. 8 A room forty feet by thirty could be lit quite cheerfully by the candles and would be dismal by the light of a single bulb. The reason is the ‘square law’ so well known to anyone who has studied physics. Ten feet away from a light source the illumination per unit area is only one-hundredth of what it is one foot away, and so on.

1976 Nature 29 Jan. 294/2 The vector voltmeters had a bandwidth of 1 kHz and employed a square-law detector following the narrow-band filter.
