4. Microwave Electronics Lab Toward Millimeter-Wave (MMW) TL Metamaterials Metal too lossy at MMW frequencies  purely dielectric  Purely dielectric  non-TEM  Non-TEM  TL approach still possible ?  If yes, how to generate dielectric L/Cs ?

5. Microwave Electronics Lab TL Approach to Non-TEM Structures: PPWG e.g. Field Analysis of Transmission Lines: Mapping from Maxwell’s to Telegrapher’s Equation Application to TE (non-TEM) Mode of Conventional PPWG Non-TEM contribution    -dep. L/Cs

6. Microwave Electronics Lab TL Approach to Non-TEM Structures: PPWG e.g. Goal: create CL-LH structure using only TL sections, i.e. stubs (possibly dielectric) C L Z2Z2 L C Z1Z1 difficult
