The effects of ground planes in modern electromagnetic applications

Abstract

1.50 Calculated local fields (absolute value relative to that of the excitation field) in the equatorial plane of symmetry for the linear self-similar chain of three silver nanospheres, Ri is the radius of the ith sphere and d i ,i+1 is the distance between the surfaces of the ith and (i + 1)th spheres. Inset: the geometry of the system in the cross section through the equatorial plane of symmetry [27]. 2.1 Patterned ground microstrip bandstop resonator (a) dumbbell-shaped (Jan. 2001) [3], (b) spiral-shaped (Jun. 2002) [4], (c) double-H-shaped (Feb. 2006) [6], (d) modified dumbbell-shaped (Sept. 2006) [28], (e) T-shaped (Sept. 2007) [9], and (f) E-shaped. 71 2.2 The V-slot patterned ground microstrip bandstop resonator [7]. 2.3 Slotted ground microstrip bandstop resonators adopted V-slot geometries 2.4 S21-parameters of the patterned ground structures when they are designed to resonate at fo = 5 GHz.
