We present the results of calculations of the penetration depths {lambda}{sub {ital a}{ital b}} and {lambda}{sub {ital c}} (the subscripts refer to the direction of the screening currents). Our model is a layered superconducting/normal metal ({ital S}/{ital N}) model, in which the two types of layers are stacked in alternating fashion. The {ital S} and {ital N} layers are coupled in a coherent fashion and the {ital N} layer is driven superconducting by a proximity effect. We calculate the penetration depths for both {ital d}-wave and {ital s}-wave order parameters for a range of interlayer coupling strengths, and we discuss the effect that the interlayer coupling has on the temperature dependence of the penetration depths. We finish by comparing our results with experimental observations of YBa{sub 2}Cu{sub 3}O{sub 7}.
