• ### Symmetric Positive Semidefinite FDTD Subgridding Algorithms for Arbitrary Grid Ratios Without Compromising Accuracy

Publication Year: 2017, Page(s):5084 - 5095
| | PDF (1842 KB) | HTML

Instability has been a major problem in finite-difference time-domain (FDTD) subgridding methods. Reciprocity has been proposed to overcome the problem but with limited success in producing a symmetric positive semidefinite (SPD) system without compromising accuracy. In this paper, we algebraically derive both 2- and 3-D FDTD subgridding operators, which are SPD by construction, and independent of... View full abstract»

• ### GPU-Accelerated Enhanced Resolution 3-D SAR Imaging With Dynamic Metamaterial Antennas

Publication Year: 2017, Page(s):5096 - 5103
| | PDF (2012 KB)

Dynamic metamaterial antennas (DMAs) offer the potential to generate diverse beam patterns with less hardware complexity than traditional electronic beam steering arrays. This paper describes an enhanced resolution stripmap mode (ERSM) synthetic aperture radar (SAR) approach for 3-D imaging with DMAs, which achieves an improved resolution in all dimensions while maintaining a larger scene size tha...

• ### New Higher Order Method of Moments for Accurate Inductance Extraction in Transmission Lines of Complex Cross Sections

Publication Year: 2017, Page(s):5104 - 5112
| | PDF (1952 KB) | HTML

A new higher order (HO) method of moments is proposed for high accuracy extraction of the resistance and inductance matrices in the multiconductor transmission lines (MTLs) of complex cross sections. The computational framework is based on the numerical solution of a surface–volume–surface electric field integral equation of magnetostatics. In order to achieve an exponentially effici...

• ### Highly Efficient 1.8-GHz Amplifier With 120-MHz Class-G Supply Modulation

Publication Year: 2017, Page(s):5223 - 5230
| | PDF (2667 KB) | HTML

A broadband and highly efficient class-G supply modulated power amplifier (PA) system with 120-MHz instantaneous modulation bandwidth operating in the 1.8-GHz band is presented in this paper. The core element is the fast class-G supply modulator which switches the supply voltage of the RF PA between three discrete levels with a minimum pulse duration of 2.5 ns. Two designs for the drain bias inter... View full abstract»

• ### Multilevel Supply-Modulated Chireix Outphasing With Continuous Input Modulation

Publication Year: 2017, Page(s):5231 - 5243
| | PDF (3547 KB)

This paper presents a dynamic characterization of a multilevel (ML) Chireix outphasing (ML-CO) power amplifier (PA) with modulated signals. The ML-CO technique combines the advantages of envelope tracking and outphasing architectures by limiting the supply modulation to discrete levels with an efficient power-DAC modulator and using outphasing for fine amplitude control. We describe an experimenta... View full abstract»

• ### Noninvasive Characterization of Solid Particle Streams Enclosed in a Dielectric Pipeline by a Bistatic Doppler Radar

Publication Year: 2017, Page(s):5244 - 5250
| | PDF (3533 KB)

This paper compares two radar configurations operating in the W-band with different antenna systems for measuring particle streams in the near-field range. A complex source beam is employed to describe the field characteristics. This new approach is used to derive the associated antenna gain and power patterns and applied in the radar equation for particle streams. We demonstrate how indoor measur... View full abstract»

• ### Ambient Backscatterers Using FM Broadcasting for Low Cost and Low Power Wireless Applications

Publication Year: 2017, Page(s):5251 - 5262
| | PDF (2950 KB)

Nowadays, the explosive growth of Internet-of-Things-related applications has required the design of low-cost and low-power wireless sensors. Although backscatter radio communication is a mature technology used in radio frequency (RF) identification applications, ambient backscattering is a novel approach taking advantage of ambient signals to simplify wireless system topologies to just a sensor n...

• ### A Full-Duplex Transceiver With Two-Stage Analog Cancellations for Multipath Self-Interference

Publication Year: 2017, Page(s):5263 - 5273
| | PDF (8160 KB)

In this paper, a full-duplex transceiver with a two-stage analog interference cancellation architecture is proposed for the prevailing wireless full-duplex communication, which enables simultaneous transmission and reception on the same frequency. This two-stage cancellation architecture jointly combines the structures of two typical analog self-interference (SI) cancellation approaches, i.e., the... View full abstract»

Publication Year: 2017, Page(s):5274 - 5283
| | PDF (3208 KB)

Modern wireless network operators are consistently looking for improvements in the wireless access infrastructure that minimize size, weight, and power. Therefore, compact multiband RF and wideband RF solutions offer an attractive role in forthcoming fifth generation networks. This paper presents a novel compact wideband RF transmitter architecture that is based upon an undersampled digital predis... View full abstract»

• ### Power, Linearity, and Efficiency Prediction for MIMO Arrays With Antenna Coupling

Publication Year: 2017, Page(s):5284 - 5297
| | PDF (5637 KB)

Modern and future transmitter architectures are being driven toward multi-input multi-output (MIMO) transceivers, which make use of several radio frequency (RF) power amplifiers (PAs) to drive an antenna array. When moving to high integration scenarios, as is expected for fifth-generation communications, the isolation between the array and the PAs is often removed. Since the array elements are ele...

## Aims & Scope

The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design..
