Investigation of microstriplike mode suppression in UC-PBG FW-CBCPW by using an electro-optic near-field characterization

Abstract

Near‐field patterns of uniplanar compact photonic bandgap (UC‐PBG) and non‐UCPBG finite‐width conductor‐backed coplanar waveguides (FW‐CBCPWs) are characterized using an electro‐optic near‐field mapping system. This system is very effective in visually showing the role of the UC‐PBG structure in the suppression of microstriplike (MSL) modes in the FW‐CBCPWs. © 2005 Wiley Periodicals, Inc.
