Transparent device is deliberately-designed electromagnetic structure that is transparent to electromagnetic wave. It can be used as a radome structure which is capable of protection antenna inside without sacrificing its performance. In this paper, two-dimensional (2D) arbitrary shape electromagnetic transparent device is designed based on transformation optics. Laplace’s equation is adopted t...

ESD design of RFIC is a great issue due to the lack of ESD device models and the interactions between ESD protection and core circuits of RFIC. In this paper, a novel co-design methodology incorporating devicelevel simulation of ESD device and RF circuit design is proposed. In this methodology, the ESD protection is incorporated into RFIC core circuit design by extracting S parameters and const...

Electrostatic discharge (ESD) failure is one of the most important causes of reliability problems, therefore the design and optimization of ESD devices have to be done. To achieve very short time to market and reduce the development effort, one tries to make use of the benefit of simulation tools. However, due to the complex physical mechanism of ESD events and the hard mathematic calculation i...

Distal protection devices appear seductively simple, elegant, and beneficial to both physicians and patients. Why would you not want to use something called “distal protection?” To not use “distal protection” during carotid angioplasty and stent placement (CAS) sounds irresponsible, like not practicing “safe sex.” In a simple world, distal protection devices would do exactly what their name imp...

We present a case of symptomatic carotid artery thrombosis treated with catheter intervention under proximal occlusion and flow reversal embolic protection. Although catheter intervention is contraindicated in carotid artery thrombosis due to the risk of distal embolization, the introduction of proximal occlusion embolic protection devices allow interventionalists to use catheter intervention w...

ESD (electrostatic discharge) protection devices as part of the device pad circuitry of semiconductors are designed for a specific wafer technology and ESD withstanding voltage. These devices are protecting semiconductor products against damages due to electrostatic discharges. After successful qualification they will be released for a usage in high volume products where they must ensure the ES...

BACKGROUND Not all new drug products are truly new. Some are the result of marginal innovation and incremental patenting of existing products, but in such a way that confers no major therapeutic improvement. This phenomenon, pejoratively known as "evergreening", can allow manufacturers to preserve market exclusivity, but without significantly bettering the standard of care. Other studies specul...

OBJECTIVES This study sought to compare the efficacy of two different cerebral protection systems for the prevention of embolization during carotid artery stenting (CAS) using a transcranial Doppler (TCD) monitoring with the detection of microembolic signals (MES). BACKGROUND Despite the introduction of cerebral protection systems, neurologic complications during CAS cannot completely be prev...
