LOSS MITIGATION IN SELF-BIASED MICROSTRIP CIRCULATORS

Loss Mitigation in Self-Biased Microstrip Circulators

Integration of the ferrite devices in the RF front-end and active antennas is hindered by the need for external magnets, biasing soft microwave ferrites.The hexaferrite-based self-biased nonreciprocal devices can operate without Bar Board external magnets at mm-wave frequencies but the currently available hexaferrite materials inflict high RF losse

Inferring human colonization history using a copying model.

Genome-wide scans of genetic variation can potentially provide detailed information on how modern humans colonized the world but require new methods of analysis.We introduce a statistical approach that uses Single Nucleotide Polymorphism (SNP) data to identify sharing of chromosomal segments between populations and uses the pattern of sharing to re
