Liquid crystals (LCs) can always reflect variable optical properties in a broad terahertz (THz) band under external electric or magnetic fields. Based on the measurements of these varying properties, we can realize electric and magnetic field sensing with very high sensitivity. Here, we theoretically and numerically demonstrate a type of electric field sensor in the THz frequency range based on the defect mode arising in a periodically corrugated waveguide with liquid crystals. The Bragg defect structure consisting of periodically corrugated metallic walls and a defect in the middle can provide a narrow transmitted peak with controllable bandwidth, which can be used for external field sensing when it is filled with LCs. The molecular orientation of nematic LCs (E7) is not only very sensitive to the applied DC electric field but also very crucial to the effective refractive index of E7. Changing the effective index can efficiently shift the frequency of the transmitted peak in the THz spectrum. The simulated results show that the sensitivity can reach as high as 9.164 MHz/(V/m) and the smallest resolution is 0.1115 V/m. The proposed sensor and its significant performance could benefit electric field sensing and extend the applications of THz technology.

Wireless Power Transfer System

The bidirectional wireless power transfer system will have many advantages to charge the batteries of the electric vehicles. In their power supply circuit, the efficiency of the inverter and rectifier is important for total system efficiency. The inverter-rectifier, which is a type of power supply circuit in this system, performs inverter operation and rectifier operation. To reduce the loss of operation modes of both, we decided to use SiC power devices that are able to reduce switching loss. However, there is a problem of high conduction loss caused by the use of SiC power devices in rectifier operation. We propose the method of parallelizing SiC-MOSFET and diode of low forward voltage, and achieved a higher efficiency.

Medan listrik yang ditimbulkan oleh peralatan listrik memiliki dampak buruk bagi manusia, medan listrik tidak dapat dilihat dengan mata manusia namun dampaknya dapat dirasakan oleh tubuh manusia, untuk mengetahui adanya medan listrik dan jarak terjauh medan listrik pada suatu peralatan listrik, maka diperlukan alat pendeteksi medan listrik. Metode yang digunakan Pada proyek akhir ini adalah menggunakan IC CMOS CD 4093 dan sistem mikrokontroller AtMega 328 P. Adapun langkah-langkah yang digunakan yaitu identifikasi kebutuhan alat, perancangan perangkat keras, perancangan perangkat lunak, dan pembagian data. Perencanaan sistem ini terdiri dari 4 bagian : sistem sensor, sistem pengolah data, sistem penampil data dan rangkaian Catu Daya.Sistem sensor menggunakan IC CMOS CD 40493 yang berfungi untuk mendeteksi keberadaan medan listrik pada peralatan yang menggunakan sumber listrik. Sistem pengolah data berupa sistem minimum menggunakan mikrokontroller Atmega 328 P untuk mengolah data yang dihasilkan oleh IC CMOS CD 4093, kemudian bagian berikutnya adalah penampil data berupa LCD (Liquid Cristal Display) dengan type modul M1632 LCD,  berfungsi untuk menampikan data yang ditangkap oleh sensor dan kemudian diolah pada sistem mikrokontroller Atmega 328 P kemudian ditampilkan pada LCD, Bagian terakhir yaitu rangkaian Power Supply, bagian ini sebagai penyedia catu daya agar rangkaian dapat bekerja semestinya.The electric field generated by electrical equipment has a bad impact on humans, the electric field cannot be seen with the human eye but its impact can be felt by the human body, to determine the presence of an electric field and the farthest distance from the electric field in an electrical equipment, an electric field detector is needed. . The method used in this final project is to use IC CMOS CD 4093 and AtMega 328 P microcontroller system. The steps used are identification of equipment requirements, hardware design, software design, and data sharing. This system planning consists of 4 parts: sensor system, data processing system, data display system and power supply circuit. The sensor system uses the CMOS CD 40493 IC which functions to detect the presence of an electric field in equipment that uses a power source. The data processing system in the form of a minimum system uses an Atmega 328 P microcontroller to process the data generated by the IC CMOS CD 4093, then the next part is a data viewer in the form of an LCD (Liquid Cristal Display) with the M1632 LCD module type, functions to display data captured by sensors and then processed on the Atmega 328 P microcontroller system then displayed on the LCD, the last part is the Power Supply circuit, this section serves as a power supply provider so that the circuit can work properly.
