Coupled closely to highly absorbing tissues, a source of electromagnetic radiation (e.g., cellular antenna) can be greatly affected by the curvature of the absorbing surface. Based on our previous planar surface approximations, we suggest an effective and relatively simple procedure for ob taining closed-form corrections for the main power rela tions involved in the presence of curved-surface absorbing tissues. The derivation is introduced by considering a two dimensional prototype models of surface and line sources radiating in the presence of a half-space and an infinite cir cular cylinder. The power absorption efficiencies of the cylindrical model are shown to be tightly bounded from be low and above by these of the half-space (planar) models.
