Fig. 1From: Cylindrical electromagnetic waves with radiation and absorption of energy a Schematics of primary concern to this study for a transverse magnetic (TM) wave along with both coordinates and non-zero field variables [8, 11]. b Three-dimensional waves around a two-dimensional disk or a ring not under current investigation [10]. c A generic curved or bent interface between metal and vacuum. Indicated are typical convex and concave portions towards the vacuum [4]Back to article page
