In this paper, we applied the Born Iterative Method (BIM) to reconstruct three-dimensional inhomogeneous objects buried in spherically multilayered media. The nonlinear inverse problem is linearized by Born approximations and solved iteratively via the conjugate-gradient approach (CG). The forward scattering problem in the spherically multilayered media is solved by stabilized biconjugate-gradient...
The dyadic Greens' functions of the magnetic vector-potential A (DGFA) for unbounded uniaxial anisotropic media are considered in this paper. It is at first derived in the spectral domain through eigenvalue decomposition method, and later transformed back to the spatial domain to get triple integral forms, which are finally simplified to Sommerfeld integrals. In order to verify these mathematical...
This work presents a cellular receiver capable of receiving three simultaneous channels with an aggregate bandwidth of 60 MHz, enabling a 300 Mbps downlink rate. The receiver has 16 RF LNA ports covering the cellular bands within the 572–2700 MHz frequency range. It supports LTE-advanced Rel-12 Cat6, HSPA+ Rel-11, TD-SCDMA Rel-9, and GSM/EDGE Rel-9. The 40 nm CMOS receiver consumes 13.7 mA and 17...
