This approach is based on the interaction of radio frequency (RF) fields with alkali atoms excited to Rydberg states. The RF field causes an energy splitting of the Rydberg states via the Autler-Townes effect and we detect the splitting via electromagnetically induced transparency. In effect, alkali atoms placed in a vapor cell act like an RF-to-optical transducer, converting an RF $E$-field strength measurement to an optical frequency measurement. We demonstrate the broadband nature of this approach by showing that one small vapor cell can be used to measure $E$-field strengths over a wide range of frequencies: 1 GHz to 500 GHz. The technique is validated by comparing experimental data to both numerical simulations and far-field calculations for various frequencies. We also discuss various applications, including: a direct traceable measurement, the ability to measure both weak and strong field strengths, compact form factors of the probe, and sub-wavelength imaging and field mapping.]]>6212616961822675<![CDATA[A Higher Order Space-Time Galerkin Scheme for Time Domain Integral Equations]]>6212618361912080<![CDATA[A Forward Approach to Establish Parametric Scattering Center Models for Known Complex Radar Targets Applied to SAR ATR]]>6212619262052500<![CDATA[Novel Polarization Rotation Technique Based on an Artificial Magnetic Conductor and Its Application in a Low-Profile Circular Polarization Antenna]]>0. Our theoretical analysis shows that the polarization rotation property of the new PRRS is due to an impedance imbalance which can be analyzed using an equivalent circuit model. In addition, two polarization rotation bands and a large polarization rotation bandwidth of 29.1% can be achieved by using the new PRRS. Moreover, the new PRRS is applied for the first time to design a low-profile dipole antenna for the generation of circular polarization radiation. Three polarization states are readily achieved. Both simulation and measurement results demonstrate good right-handed circular polarization with a broad axial ratio bandwidth and a large axial ratio beamwidth in both the xoz and yoz planes.]]>6212620662163538<![CDATA[Coherent Processing and Superresolution Technique of Multi-Band Radar Data Based on Fast Sparse Bayesian Learning Algorithm]]>6212621762272269<![CDATA[Electromagnetic Analysis for Conductive Media Based on Volume Integral Equations]]>6212622862351617<![CDATA[On the Analogy Between Vehicle and Vehicle-Like Cavities With Reverberation Chambers]]>6212623662451506<![CDATA[Electromagnetic Focusing and Imaging in Stratified Media Using Gradient Phase Profiled Conjugating Lens]]>6212624662551929<![CDATA[Closed-Form Analysis of Artificial Dielectric Layers—Part I: Properties of a Single Layer Under Plane-Wave Incidence]]>6212625662642495<![CDATA[Closed-Form Analysis of Artificial Dielectric Layers—Part II: Extension to Multiple Layers and Arbitrary Illumination]]>6212626562732234<![CDATA[Perfect Co-Circular Polarization Reflector: A Class of Reciprocal Perfect Conductors With Total Co-Circular Polarization Reflection]]>6212627462811615<![CDATA[Discrete Helmholtz Decomposition for Electric Current Volume Integral Equation Formulation]]>2-conforming unknown current into orthogonal functions. The decomposition shows that the solenoidal, irrotational and harmonic subspaces scale differently with respect to the material parameter. This has a negative effect on the conditioning of the system, and thus, the convergence of the iterative solution slows down with increasing permittivity. We construct discrete decomposition operators, and use them as a preconditioner for the electric current volume integral equation. The eigenvalues of the resulting system are almost independent on the permittivity. Numerical examples show that the proposed preconditioner improves the condition number and decreases the number of iterations required to solve the system. However, efficient evaluations of the projection operators require additional regularization techniques such as algebraic multigrid preconditioners.]]>6212628262891918<![CDATA[Excitation of Complex Modes of Periodic Structures Using Inhomogeneous Plane Wave Scattering in Fast and Slow Wave Regions]]>6212629062981460<![CDATA[On the Development of Nonoverlapping and Stable Hybrid FETD-FDTD Formulations]]>6212629963062002<![CDATA[3-D Discrete Dispersion Relation, Numerical Stability, and Accuracy of the Hybrid FDTD Model for Cold Magnetized Toroidal Plasma]]>6212630763162404<![CDATA[Performance of a Massively Parallel Higher-Order Method of Moments Code Using Thousands of CPUs and Its Applications]]>2) and O (N^{3}), where N is the number of unknowns.

A new approach is discussed to estimate N_{h} and ΔN from the analysis of the dry and wet components of N_{s} , which gives better results for certain cases. Results are compared with those obtained from existing linear and exponential models in the literature. The investigation focusses on three layer heights at 65 m, 100 m and 1 km above ground level. Correlation between the components of N_{s} with both N_{h} and ΔN are studied for each atmospheric layer.

Two parasitically coupling strips are added to excite one additional resonance mode. Bent dipole antennas and feeding structures are fabricated on the different planes of the substrate to embed two L-shaped stubs, thus resulting in improvement of the impedance matching condition. After careful optimization of the geometrical parameters of the antenna, the resonances are merged and thus, a wide impedance bandwidth is obtained. The measured -6-dB bandwidth of the antenna in free space is 615 MHz (80.4%).]]>6212651565191275<![CDATA[De-Polarization of On-Body Channels and Polarization Diversity at 60 GHz]]>621265196523536<![CDATA[Closed Form Expressions to Find Radiation Patterns of Rectangular Dielectric Resonator Antennas for Various Modes]]>y modes.
