The paper considers the constructive implementation of the nanophotonic sensor of comprehensive application, proposed by the authors earlier and investigated using computer simulation. Here we investigate one of the constructive solutions of a supersensitive pressure sensor based on nanostructures, providing miniaturization of sensors and their application in various technical products. Based on the previously conducted mathematical simulation of the process of high-frequency electromagnetic radiation propagation through a nanocones array, which is the essential element of the proposed design, justified decisions about the overall dimensions of the structure, its internal structure, and the optimal frequency of the field excitation source are made. This work solves, in particular, the problem of protecting the sensor’s internal structure from external electromagnetic fields. Employing solid-state modeling, the linearly reciprocating motion of the sensor plates under external loading in the proposed device design is confirmed.
The paper considers the further development of a nanophotonic supersensitive sensor proposed by the authors earlier. The sensor is oriented for a wide range of engineering applications. The main idea of the device is to estimate the external pressure loading of the sensor by the electromagnetic field measurements. The nanophotonic sensor structure is irradiated by the electromagnetic source operating in the frequency domain. The light beam is passing through the internal cone structure of the sensor, and the output electric field is measured. The proposed mathematical modeling gives the opportunity to connect the radius of the inclusion in the sensor longitudinal section and the output electric field intensity in the reference measurement’s point. A 3D simulation of high-frequency electromagnetic wave propagation in a photonic microsensor structure was performed in a formulation close to the real one in the following paper. The mathematical modeling is carried out by the vector finite element method implemented in the author's software. The conducted numerical research allows us to make design decisions about the optimal overall dimensions of the sensor and the operating frequency of the electromagnetic radiation source.
We propose the operating principle of a nanophotonic highly sensitive microsensor for a wide range of applications in technology, electronics, medicine as a sensor of pressure, temperature, vibration, blood pressure, etc. Computer simulation of the visible radiation interaction with the sensor nanostructure was carried out using the author's software product. The software is based on the modern mathematical apparatus of the vector finite element method.
We present the computer simulation of an electromagnetic wave propagation process in some complex medium similar to optical material in the form of microlenses for nanophotonic devices. Numerical modeling is performed in the terahertz frequency range corresponding to visible radiation. The proposed author's software product is based on the modern mathematical apparatus of the vector finite element method.
