“…Another calibration issue occurs as the AFM or STM tip scans across the sample and carries with it RF signal changes that are associated with the topological properties of the sample itself, which must be separated from sample electrical properties. 8 Solutions include scanning the sample stage without the sample present and subtracting point by point, or most recently, using a novel analytic method coupled to the probe geometry [42].…”

If the Twentieth Century boasted of the Space Age and the Computer Age, the Twenty-First Century is certainly starting off with the Age of Biology, or at least Biochemistry. The enormous impact of CRISPR (clustered regularly interspaced short palindromic repeats), LAMP (loop-mediated isothermal amplification), cryo-EM (electron microscopy), and many other nano-techniques in the biosciences is transforming the world in so many ways, not the least of which are the diagnostic tests and vaccines that are helping our global pandemic. Microwaves are huge compared to the likes of optical wavelengths and, at least for the world of bio-spectroscopy, being able to perform and take advantage of standard microwave materials measurements at a cellular (micron) and even molecular (nanometer) scale has been a major impediment to applications for this well-developed electronics technology and instrumentation. In the early part of the 21 st Century, the fields of AFM (atomic force microscopy) and SMM (scanning microwave microscopy) came together and spun off a handful of commercial applications and instruments stimulated by some very clever engineering and bio researchers and partnerships. In this, our fourth tutorial article in our continuing series on the ubiquitous presence and applications of microwaves, we take a look at the origins, instruments, biological applications, and goals for "nano-microwaves" the use of microwaves at nanometer scales.INDEX TERMS Scanning microwave microscopy (SMM-VNA), THz near-field scattering microscopy (SMM-THz), near-field microwave imaging, near-field THz spectroscopy, nano-microwaves.This article has been accepted for inclusion in a future issue of this journal. Content is final as presented, with the exception of pagination.

In this article, we propose a quantitative, non-destructive and noninvasive approach to obtain electromagnetic properties of liquid specimens utilizing a home-designed near-field microwave microscopy. The responses of aqueous solutions can be acquired with varying concentrations, types (CaCl2, MgCl2, KCl and NaCl) and tip-sample distances. An electromagnetic simulation model also successfully predicts the behaviors of saline samples. For a certain type of solutions with varying concentrations, the results are concaves with different bottoms, and the symmetric graphs of concave extractions can clearly identify different specimens. Moreover, we obtain electromagnetic images of capillaries with various saline solutions, as well as a photinia x fraseri Dress leaf.

“…Over the past decade, one of the most significant advances in the field of microwave testing has been the emergence of scanning microwave microscopy [1][2][3][4][5][6][7][8][9]. There are two main types of scanning microwave microscope, categorized according to the source of the microwave signals at the scanning tip, with one type using a microwave resonator coupled to the tip of the probe using a small aperture and the other using a coaxial transmission line directly attached the tip of the atomic force microscopy (AFM) cantilever.…”

In the field of materials research, scanning microwave microscopy imaging has already become a vital research tool due to its high sensitivity and nondestructive testing of samples. In this article, we review the main theoretical and fundamental components of microwave imaging, in addition to the wide range of applications of microwave imaging. Rather than the indirect determination of material properties by measuring dielectric constants and conductivity, microwave microscopy now permits the direct investigation of semiconductor devices, electromagnetic fields, and ferroelectric domains. This paper reviews recent advances in scanning microwave microscopy in the areas of resolution and operating frequency and presents a discussion of possible future industrial and academic applications.
