We explore the optical and electrical characteristics of monolayer graphene by using pulsed optoelectronic terahertz time-domain spectroscopy in the frequency range of 325–500 GHz based on fast direct measurements of phase and amplitude. We also show that these parameters can. however. be measured with higher resolution using a free space continuous wave measurement technique associat... https://cosmeticssquadets.shop/product-category/shaving-foam/
