Experimental Testing Of A 3d-Printed Metamaterial Slow Wave Structure For High Power Microwave Generation, Antonio B. De Alleluia
Electrical and Computer Engineering ETDs
A metamaterial (MTM) high power microwave (HPM) vacuum electron device (VED) was developed using 3D printing technology. The specific geometric pattern of the source can produce both negative permittivity and permeability to interact with a relativistic electron beam. The electron beam is generated using a pulsed electron accelerator with a maximum energy of 700 keV and lasting approximately 16 ns. The design of this novel VED consists of a circular waveguide loaded with complementary split-ring resonators in a linear periodic arrangement in which the relativistic beam travels guided by a magnetic field. The electrons interact with the MTM producing electromagnetic …

Study and control of light matter interactions at the nanoscale is an extremely active topic of research as it can create intriguing new opportunities for sensing, optoelectronics, nonlinear optics, and other nanophotonic devices. Various platforms have been investigated to study light-matter interactions at the nanoscale. The most recent explorations in research come from one platform, metasurfaces – planar equivalents of three dimensional metamaterials. Previous studies of strong light matter interaction have been demonstrated on metallic metasurfaces. However, there are little experiments demonstrating strong light-matter interaction in all dielectric metasurfaces. We present a study demonstrating strong light-matter interactions in a hybrid …
