In vivo sensing and imaging of human tissues using micro- and/or nano-sensing platforms constitutes one of the biggest challenges in the field of bioengineering for the next several years or decades. Such sensing platforms mounted on micro- or nano- robots not only will enable real-time monitoring of biological tissues, but it may also play a pivotal role in the localization and treatment of cancerous cells inside of the human body. Enabled by the recent development of novel Compressive Antennas, in this paper we present some preliminary results showing the feasibility of hematologic characterization and 3D imaging of red blood cells affected by different disorders using a nano-sensing electromagnetic platform operating at optical frequencies.

In this paper, the characteristic basis function method (CBFM) is applied to instead of conventional MOM for MLFMA implementations. CBFM includes the mutual coupling effects among different subdomains directly by constructing the high level basis functions, Use of these basis functions leads to a significant reduction in the number of unknowns, and results in a substantial size reduction of the coupling matrix;This reduces matrix size improves the convergence properties. The MLFMA is introduced to speed up the matrix-vector multiplications. The advantages of applying the CBFM with MLFMA are illustrated with numerical simulation. The results demonstrate the efficiency and accuracy of the proposed method.

In this paper local multilevel fast multipole algorithm (LMLFMA) based on a novel improved electric field integral equation (IEFIE) is developed to achieve fast and efficient solution of electromagnetic scattering from 3D conducting structures. A well-conditioned matrix is constructed in the IEFIE by adding the principle value term of magnetic field integral equation (MFIE) operator into traditional EFIE operator. Only several update steps for the current vector are required to attain a reasonable solution. To further speed up the computation of matrix-vector multiplications in the iteration, LMLFMA is applied. The present method attains much faster convergence of iteration than traditional EFIE and less computational complexity of matrix-vector multiplications than MLFMA, and it still keeps good accuracy. Numerical results show the validity and efficiency of the present method.

To further expedite solution of electromagnetic scattering from conducting structures with slots, a novel improved electric field integral equation (IEFIE) is developed to reduce the iteration time in multilevel fast multipole algorithm (MLFMA). By adding the principal value term of magnetic field integral equation (MFIE) operator on the both sides of the EFIE operator, a well-conditioned improved EFIE operator is constructed. To achieve a reasonable accuracy, only several update steps for the unknown current is required. Numerical results demonstrate the validity of the present method.
