hq37vm4494h	Jiahao Huang	Low-Dispersion Metamaterials for Wideband Gradient-Index (GRIN) Lens Antenna	2022		.txt	text/plain	148	7	42	The proposed 40 GHz GRIN metamaterial in this thesis is based on printed circuit board (PCB) technology, with relatively low cost compared with other fabrication methods such as layered dielectrics and perforated dielectrics. Gradient-index (GRIN) lens antennas leverage spatially varying refractive structures to generate high directivity beams.	cache/hq37vm4494h.txt	txt/hq37vm4494h.txt
