Characteristic Measurement

Hardware-software subsystem designed for MOSFETs characteristic measurement and SPICE model parameter extraction taking into account radiation effects is presented. Parts of the system are described. The macromodel approach is used to account for radiation effects in MOSFET modeling. Particularities of the account for radiation effects in MOSFETs within the measurement and model parameter extraction procedures are emphasized. Application of the subsystem is illustrated on the example of radiation hardened 0.25 μm SOI MOSFET test structures.

Physical Phenomena

Metamaterials, including their two-dimensional counterparts, are composed of subwavelength-scale artificial particles. These materials have novel electromagnetic properties, and can be artificially tailored for various applications. Based on metamaterials and metasurfaces, many abnormal physical phenomena have been realized, such as negative refraction, invisible cloaking, abnormal reflection and focusing, and many new functions and devices have been developed. The effective medium theory lays the foundation for design and application of metamaterials and metasurfaces, connecting metamaterials with real world applications. In this Element, the authors combine these essential ingredients, and aim to make this Element an access point to this field. To this end, they review classical theories for dielectric functions, effective medium theory, and effective parameter extraction of metamaterials, also introducing front edge technologies like metasurfaces with theories, methods, and potential applications. Energy densities are also included.

ABSTRACT The presence of oestrogen inhibitory activity in oat hay (Avena sativa) and Fahli clover hay (Trifolium alexandrinum var. Fahli) has been established. The antioestrogenic effect was demonstrated by the inhibition of uterine weight increase in rats (Astwood test) in response to oestradiol injected together with the above mentioned plant extracts. The extraction procedures are described in detail and the possible biological implications of antioestrogenic and oestrogenic activity in fodder plants is discussed.
