✦ Synopsis

interface and a vertical electric dipole (VED) source were considered. The reflected field was obtained from a reflection-image source, which is the same as the case when a Veselago medium is replaced by a corresponding regular medium with positive medium parameters. The transmission-image problem can be handled by splitting the Veselago medium in two regions, each with its own image. In the region between the interface and the mirror point of the original source, the transmission image is not a source but a sink, which means that instead of power emerging from it, it is absorbed by the image. For the region below the mirror image of the original source, the transmission image is a dipole source. Combined, the two transmission images act as a fan which sucks energy from one half-space and blows in into the other half-space.

## Abstract In this letter, a compact low‐pass filter (LPF) with wideband rejection using double‐step impedance shunt stub (SISS) and barbell‐type defected ground structure (DGS) is presented. This proposed LPF has similar characteristics in bandwidth, but good wideband rejection and cutoff sharpne
